Last month I tried to preorder some of the ISO-T club paks and due to the Pro Series shafts being backordered had cancelled and figured I would wait the two weeks that was quoted to me. I again put in an order as I had scheduled three fitting8 next week. Not only are the stock shafts still not available but now the 10.5 heads are back ordered. Its beyond frustrating to have to call customers and say product isnt available after such a build up and an important product release. I’m trying to get back into fitting in a big way and it’s not helping. Trying to build a customer base and credibility in this day and age of instant feedback postings is brutal. Trying my best to not look like an idiot.

I’m sure you struggle for space at the forging plant and the same goes for shaft scheduling… but this hurts.

Unfortunately I cancelled $650 worth of supplies today.. with at least a months wait for a 10.5 head. Its the height of the season with zero product…..

Fit to YouGolf 5 Posted June 13, 2019 2 Comments

I will be posting my review on YouTube on the ISO driver soon. Like many on this forum the CT 250 (flight control in my case) sets the benchmark for me. The ISO at 10.5 came close in performance, but spun a bit more (300 rpms) than my CT, at my SS of 95 mph. I think the design of the head may lend itself to choosing a lower loft than what a golfer usually plays (at a similar speed and launch angle…I was at 16 degrees pretty consistently when testing with 2 different shafts). Keep in mind this is one golfer’s/fitter’s conclusion. I am interested to hear from others. Dave (Fit2YouGolf)

I have some numbers measured with the GSA PRO app but it does not record launch angle and spin rate……never the less interesting. Yesterday I made 5 swings each with the ISO-T , 2016 TM M2(my current gamer) both with Fujikura pro 60 stiff, and my old gamer the CT-250 with a graffaloy platinum 75 stiff. CT -250 average swing speed 94, average carry 222.4. TM M2 average swing speed 97.75 average carry 235.25. ISO-T average swing speed 99.2 average carry 238.2 . Of the 3 the launch of the CT-250 was the highest followed by the M2 and the ISO -T the lowest. So for me it is different than Fit to You in that for me the ISO-T launces low. It would be interesting to see the numbers on a real launch monitor. Of the 3, I hit the M2 the straightest and the CT-250 a little left while the ISO-T for me definitely had a fade bias. Of the 3 heads the CT-250 sound and feel was by far better , followed by the M2 with the ISO-T sound and feel the least pleasing(it was definitely firm) Swing speed numbers were predictable in that the graffaloy is a heavier shaft. All 3 drivers are set up at44-1/2 inches D2 swing weight. If I can get on a real launch monitor I will report those numbers. Regardless I will be keeping and continuing to tinker with the ISO-T . Thanks for all you do and for this forum !

Interesting numbers. When you get a chance to do the same on a launch monitor, please share. When I get a chance, I will do the same. Our testing on the ISO-T has shown it does launch lower for the loft designations than other drivers and the spin is usually slightly lower as well, which was the design goal with this driver. Of course the numbers can vary from player to player. I know for me, the 9.5 with the shaft I am using (rouge Silver 130 MSI TS Flex) puts the launch and trajectory right where I want it, in that same window I had with the 8 degree (actual was 8.5 degree on mine) CT250 with the Diamana BF Sereis 60 S. As for the sound, I am convinced we all hear different things. We went through 3 iterations and the final was unanimously given the thumbs up with our test crew. Solid and explosive were the adjectives used to describe. As most drivers do, if you hit it off the toe or heel it might have a different tone, but most do. I always thought the CT 250 was a little loud. Not bad or offensive, just a little louder than some other models. The ISO-T, when blind tested by our crew, was chosen as a better sound than several OEM drivers, which I won’t name. Still, sound is in the ears of the beholder and any given driver might sound great, or not, to any given player.

Britt,

Thanks for your reply to Popeye and his frustration with supply. As to my performance issues I very much appreciate your concern. I will agree that the ISO-T is a much better performing head than both heads in the ST-2 line . I will do some testing side by side with my CT-250 and follow up afterwards. My gamer driver now is the 2016 Taylor made 10-1/2 degree M-2 shafted with a Fujikura pro 60 stiff at 44-1/2 SW d-3. I have the identical shaft in the ISO-T at 44-1/2 and with the 14 gram weight and golf pride cp 2 pro midsize grip at SW D-2. I must admit that I had to tinker with the CT 250 before I found the right shaft which ended up being a Graffaloy platinum stiff . The set up and look is a lot different with the ISO-t than the M2 … maybe I just need more time to find the right combination in shafts, and if not I appreciate your offer to return the head. Just a thought, could it be that the CT- 250 with a .350 hosel bore was just a more stable platform?

Thanks for the comments and understanding. No evidence that a .350″ hosel is a more stable platform. The .350 era kind of came and went and was born out of paranoia that light weight graphite shafts were going to break and needed a bigger tip section. OEM’s started it, then the shaft manufacturers started selling the .350″ tip options to fit the OEM drivers, etc. Also, by using .350″ tip diameters the shaft manufacturers could use lower modulus material in the tip sections, saving a little money. Happy it has turned back to .335″. No difference in stability.

As a side note, played my second round with the ISO-T this morning. No reservations in saying, for me, it is as good a driver as I have ever hit. First 9.5 degree driver I have ever been able to play with. Always had to use an 8 degree, which is why I stayed with the CT 250 for so long. Trajectory with the ISO-T 9.5 is spot on. The Taylor Made you mentioned is a fine driver. If you do tinker around with the ISO-T, be sure to let me know what you find out. I’m hoping you will find a combo that performs as well as mine is for me. If not, the offer stands to return it.

Britt, the sound of the ISO-T is terrific. Solid, with some depth. Good volume but not too loud. I think I was able to capture it pretty well in my YouTube review video.

First, let me apologize for the delays. No excuses, just the fact that demand exceeded what our initial forecast was. We air shipped the initial quantities in. In hindsight, we should have had more shipped. Also, the materials used and the method of manufacturing this product requires special treatment. The Isothermal Heating and the ovens used required some modifications we were just made aware of, which delayed next shipments by about a month. I know that is our problem, not yours, but sometimes when new innovative processes are used unforeseen things can happen.

As far as the performance Billy has experienced, I am surprised. Not sure why it’s not working for you, but sometimes a club just might not work for a player. I played the CT 250 until the ISO-T. It’s the first model of driver we have produced that, for me, performs better. Required me to test with different shafts, but found a combination that worked (and the shaft is different from the one I have used for years in the CT250). Technically, we produce all our drivers to perform to the limit of what is allowable by the USGA. The CT 250 did, the ST Series all did, and the ISO-T does. It’s the same for all categories of clubs. Not every club released is going to work for everybody. I would love to have a chance to see you, Billy, hit the CT 250 and the ISO-T and compare the specifications and ball flight numbers to see if we could identify what the variance is. Would be interesting. If you are unhappy with the ISO-T, I would prefer that you contact us and send it back. If it has not met your expectations, I’ll offer you the opportunity to return it for a refund.

Thanks for the honest feedback. I do appreciate it. Of course we hope everything we do will work for everyone, but we know that just does not happen, for any manufacturer. Still, I am extremely proud of the product we have developed and produced.

Popeye….I understand your frustration. However I must say that this head for me does not live up to the huge perhaps unwarranted expectation that I had for this realease. My early opinion 10 days in and on my third shaft combination with the 10.5 is one of disappointment. For me this head is maybe a step up from the previous generation of Maltby driver models but not even close to the CT 250. I have played Maltby products for over 18years and so far this head is one of my biggest disappointments with Golfworks.Maybe I will change my mind and I hope I do!
