The only problem with the tour 90 shaft is you will lose 2 or 3 points of swing weight.  If you don't want that try the XP 95 shaft, about the same weight but built to maintain swing weight.

Although you do not mention what type of launch you are looking for or what shaft you are currently playing, I have found the KBS C-Taper Lites in stiff perform well in my 714 AP2's.  This is also mid-launch, slightly heavier than 102g, but provides the flight and dispersion that I was looking for when fit for the irons.

Thanks for the replies.  I have the XP 95 in my 712U 3 iron, and I really like it, but wanted some opinions of others.  I wish I could get fit, but I travel 5-6 days a week, and there really isn't anyone close to me, other than Golf Galaxy and Golfsmith.

I was looking at a set of 714, and re shafting them.  I think I will wait until spring and try and find a place to get custom fit.

Thanks.  i think I am going to wait until spring and try and find somewhere to get fit outside.

The Titleist shaft chart shows the various comparisons of shafts plotting spin vs launch.  Obviously, a fitter can determine the best results, but the chart should be a good starting point for what you are looking for.  I played png Eye-2's for almost 30 years with their ZZ-Lite Stiff shafts.  I hit the ball really high, with an 8-iron (40deg) around 150-155 yds.  I tried a few of the new Ben Hogan Ft Worth 15 irons in Tour V Stiff 110 and Tour V X-stiff 120, and hit them great.  When I saw Titleist's shaft comparison chart, I knew DG was the way to go with one of the lowest launches.   I just switched to some AP2 714s with DG X100 shafts, and couldn't be happier.  I only have 2 range sessions with them so far, but, In addition to that great forged feel I've been missing all these years, I think I get better dispersion and precision with the X-Stiff's.

Best of luck.
