Hi,

I have read that Wishon is producing a single-length iron set, with irons 7-5 having high COR faces, to make up fo the loss of distance.

I thought that I could build a single-length iron set with KE4 s heads, as I could combine the weight screws in order to make all the heads weigh the same, but I was wondering if not having high COR faces would really affect distance gapping in the low lofted irons.

I was also wondering if it could be a good idea to use true temper spinner shafts for the entire set, since I like the feeling and the set would be at 36.5 inch length.

Any ideas?

Thanks,

Antonio

First, I have no real data, nor have I seen any data to support, that a “high COR” face on an iron generates any meaningful distance increase. It is important to understand the more loft you have on a club, any club, the more indirect or oblique the hit is. This means there is less direct impact. The less direct impact, the less affect any kind of face deflection can have on ball speed. I believe the company you referenced is also making the single length set 36.5″. In my opinion, those long irons better have one heck of a high COR and not very much loft to make up for the difference in distance. Again, just an opinion, based on what we understand about the affect of loft and length and face deflection on distance. We have not tested. To answer your question, I do not believe the advertised “high COR” will affect the distance gapping in the low lofted irons. Loft will affect distance gapping far more than any COR in an iron. As far as the Spinner shaft, I suppose you could, even though it was designed for Wedges. Not sure anyone has ever tried.

Thanks Britt,
Today I took a KE4 four iron and put a FST 125 PRO shaft cut at 37″.
I put about 25grams of led tape as i didn’t have heavy enough screws, I moved the lie 2° upright. The shaft was tip trimmed for a 4 iron. The result was very good, although trajectory was slightly lower and I probably lost 5 yards, consistency was higher and so was distance control and direction. I’m tempted to go ahead and but heavy screws and try the full set from 9 to 4 iron leaving out the wedges, as I don’t feel comfortable in using such long shafts on wedges.
I thought of tip trimming the shafts as indicated, each iron with a different stepping, and making the lofts 4° between all irons, including the long ones. I thought of doing so in order to find decent distance gapping. (do you think it’s ok, or should all shafts be equally tip trimmed?)
Any other suggestion?
Thanks,
Antonio
