Hi Britt, for reference here is our previous discussion.

KuroKage HBP wood shaft, R to A.

I did go with the A flex and it worked fine for most of last season. Due to recovery from injury, swing changes and fitness training I’ve gained some speed back. Now the A flex is not working, inconsistent face contact , high fade or draw and short by ~10 yards . I put an R flex back in and it’s not working either. Low left, can’t feel it load. So it appears I need a flex between R and A.

I tested both shafts on my Mitchell machine, 5” clamp, for CPM with a 3W-213 grams, shafts both tipped 1/2”. R flex is 251 cpm and A flex is 231 cpm, both in the strong FLO position. I did note in the referenced thread you stated there is 15 cpm between flexes. Seems like a lot , and 20 is more. Some other makes and models seem to be in the 8-10 range. I also tested the 7W A shaft, (tipped 1.5”) extended to 43” with the 3W head and it only raised the flex 3 cycles. With only 3’ PTS I don’t think tipping will get me to a mid flex.

As a reference point you might recall I put a PX Cypher 40gm A flex shaft in my driver and that did work for a while, but then experienced the same poor results as with the KK A flex in my woods as my speed increased. I installed an Evenflow Blue 55gm A flex shaft and got some dramatic improvement, contact, trajectory and distance.

Hard to find these Evenflow shafts now, is there a shaft with a similar profile available now that you could recommend ?

I’m a condundrum, I do like the KK HBP shafts , hit them well when my swing matched, but need an in between flex, or something else similar with a mid flight.

Im off to Scotland in April so need a solution. I can test shafts indoor on a sim , but will have no opportunity to actually play before the trip.

Looking forward to your help with this.

thanks.

p.s. I posted a previous similar message, but when I went to use the edit function, I got a message along the lines of “message can’t be found”. Sorry if this ends up being posted twice.

In an A flex, the Tensei CK Blue 50 A (MR0068) is almost identical in profile to the KK HPB black 50 A. So that would be an option. Of course the HPB can work if you want to take the A flex and trim it a little more. You don’t have much room to trim more, but a little. Can’t tell you exactly an additional 1/2 off that shaft will make a difference. Probably not that much. The Proforce in the A flex is pretty close and could work. It’s just slightly firmer in the tip, so that actually might work out, being an A flex with a slightly firmer tip than the KK or the Evenflow.

I don’t have the profile numbers on the HZRDUS Red CB G4 shafts yet. Haven’t had time to get them done, so I can’t give you exact comparison numbers for that shaft. Based the other HZRDUS Red products in the past, my guess is it will be stiffer in the A flex than the KK or the Tensei.

I scanned the data base looking at profiles and found three that ight work. The Rapport Core Blue 50 in the R flex and is just a fraction softer than the Evenflow. The ProForce V2 by UST in the R flex and is a fraction firmer than the Evenflow. And, the Fujikura Vista Pro 55 in the R flex, which may be slightly softer in the butt section, slightly firmer in the mid section, but the overall deflection number is exactly the same as the Evenflow. I did not loo at all shafts, but the dozen or so I looked at these seemed to be the best matches for what you are looking for.

Hope this helps.

Hi Britt, appreciate the comparable shafts info, I do have a couple followup questions.

The Rapport and the Vista pro are designated high launch, so those are out. I’ll look at the Proforce. You quoted all in R flex, but I think A flex is closer to my needs. Do your comments apply to the Proforce as well in the A flex?

So I take it that there’s no way to make the KK HBP work? Just curious why the CPM’s are so far apart.

I see the new Project X HZRDUS Red CB G4 Red shafts, how do they compare with the Evenflow Blue and the KK HBP shafts ?

Thanks.
