Ok, thanks for the help.

I spin my current irons a lot, my 7 iron is about 9500 rpm?

Is that to much?

I've tried the C-Taper X-flex, compared to my usual X-100's. They didn't feel too bad. My launch and spin were good. BUT...I'm sticking to my X-100's. 

Hi

Can you post your numbers? Ball speed, launch and spin with both shafts? Also, which head were you hitting? I've got some AP2 with C-Taper X on order and I'm just curious. I've been playing 710MB with PX Satin 7.0 and I was looking for an ever so slightly lower spinning shaft but with better feel.

Thanks

For what its worth, the x100's do play softer than the c-taper in x flex.  If you want a more accurate comparison, compare the x100's to the c-taper X soft stepped once.

We have tested the C Typre extensively due to the hype and the nice looks, a lot of people want to play clubs/shafts because the look nice. In the right club and swing combnation they are great, for Steve Stricker they work great in the AP2's, we have tried them in the AP2's and for some people it worked and for others not.

I had them in S flex in MP 63's and they did not work for me, the reason I used S flex is that they play about 1 flex more stiff than normal KBS Tour. The problem was in the longer irons where the flight was to low. I put my KBS tour's back in and they work very well with the MP 63's.

I the replaced the PX 6.0 Flighted in my CB1 irons with the C Typre's. this is one of the best combinations we have tested with the C Typre's. It is like shooting arrows. the Clubs are MOI weighted and not swing weight weighted. so the 3 irons is D2 and the PW at D6. I

 also have them in my Miura wedges 53 and 57 degrees and they work very well. we ahve now tested C Typre in the new MB2 irons. like the CB1's they are fantastic combination where the KBS Tour (smoke) in the MB2's showed some dispersement issues.

So in the right combination with the right player, they are great, but they are not for everyone. Our view is that people play them to stiff. Dont hard step or soft step them!

The bit about the right combination for the right player can be said of any shaft, not just the c-taper. There is no "magical" shaft that will make any player better. As for your statement about not hard stepping or soft stepping them, the question that I have for you is why not? If you want to dial in a shaft to a specific FCM, that would be the only way. Or if you prefer the weight of a 130g shaft (c-taper X) but want it a bit softer, then why not take the x flex c-taper and soft step once or twice. Or if you prefer the slightly lighter weight of a 125g shaft (c-taper S+) but want the flex of an X, then why not take the S+ shaft and hard step once? There are many variables when dialing in shafts and to say "Don't hard step or soft step them" is just a silly general statement to put out there.

I personally play with mizzy 68's with c-taper S+ shafts straight in, however my vokey wedges (by the way Mr. Titleist, I also game the 910 drivers and fw woods and a SC putter :)) are the c-taper S+ soft stepped twice which gives it a flex slightly softer than if I was to put the c-taper S straight in. Why would I not just put the c-taper S straight in? For the slightly softer feel of the S+ssx2 versus a S straight in, as well as to maintain the heavier weight of a S+ shaft versus the 5g lighter S shaft.

I used to play dg x100, then switched to c taper s with 712 cb. Is there anyway of making the club head slightly heavier, as they feel very differently balanced. I guess this is how the shaft lowers spin, but i feel this looses feel.

10 g is 1/2 swingweight point.

All the rest of the swingweight parameters I've been right on for some time (grip weight, change in shaft length, head weight change) but got bum info on the uncut shaft weight. 

I did try a KBS C-Taper shaft vs a DG R300 on a G15 7 iron at a fitting station about 6 months ago and they both felt good.  I've basically "grown up" with a DG R300 or TT Lite XL regular and they are a little less of a strain on the pocketbook.  TT LIte XL is equivalent to the ZZ Lite.  In regards to swingweight, sometimes the diff between a light shaft and a DG R300 is minimized because the butt end is thinner (less grip weight = higher swingweight; TT Lite XL vs DG R300 on two identical 6 irons showed a 2 swingweight point diff with the former being higher; the uncut weight @ 43" with TT Lite XL was 128g and the DG R300 was 127 @ 41" and both had parallel shafts).

Just for everybody's info, I got into club making in 2009.  I got some components from Golfsmith and Golf Works and constructed a set of irons, a lob wedge, 3 hybrids and two fairway woods (they had a closeout at Golf Works with Toski Target T-6 7 and 9 wood heads).  During this endeavor I had some assistance with a local fitter/repair person and actually weighed clubs during the process.  So I have a spreadsheet created with lengths and lie angles from the driver down to the X wedge. You might say that I am a bit of a "golf mad scientist" (always been a bit of a tinkerer since youth and it parlayed into a career in the Navy with a follow-on career as an Electrical Engineer).  

I currently have x100s and I'm going to have c-taper s+ shafts put in a set of AP2 irons...will the swing weight be about the same or will the s+ c-taper shafts decrease the swing weight?  I like a heavy club head, but I'm hesitant about putting c-taper x stiff shafts in if they're too stiff.

Off the top of my head the c-taper S+ is 5g lighter that the X100, with this you will loose 0.5 SW point. You will have to check the balance point as well as I think c-tapers come out another half point lighter.

Titleist should be able to get this weight back up to D2 though with tip weights.

Does anyone know how the x stiff kbs tours feel and play in comparison to the dg x100, thanx

Ok,

So i maybe should try these shafts?

Im considering the new MB´s with the C-Tapers.

Could them bring my spin down?

Ryan, I play the apt 710 and I'm one of those people you referenced above that gets too much spin and too high a ball flight with the ap2/s300 combination.  I've been hitting other shafts/clubs the past 3 weeks and am close to moving away from the ap2.  Today, I hit the C-Taper for the first time (in a TM MC) and absolutely loved it.  My backspin was in the 5600 range and sidespin around 300 with a ball speed of 120 and a launch angle of around 17.  My question:  instead of replacing these irons, if you were me would you consider changing the shafts to the c-taper?  Would I be able to ship these to Titleist to do so? And lastly, do you think it would likely lower my spin and launch a bit over the s300s?  Many thanks.

Ok thanks for all the help. 

What flex should I use? I have a driver SS of around 108-110 mph. 

Is there any other shafts that give about the same low launch and spin?
