Hi Eugene - 

The NS Pro 105T is a higher launching shaft.  Based on your numbers you may want to look at the stiff flex option in the 105T first.  

Your best bet is to find a local Titleist fitting partner in your area and work with them to determine which shaft is best suited for you.  Your spin is much too high for your ball speed, which is most likely causing the ball to balloon.  Getting your spin rate down closer to 6000 would provide better launch conditions.

Hi Nick,

Thank you for reply.

I am confused because I made three different fittings these last weeks :
- With a RAZR Forged with shaft TT DG R300
- With a MP 58 with shaft KBS
- With a Titleist (AP 2) with shaft  NS Pro 105T regular
My lowest trajectories were obtained with MP58.
My preferences go to the sensation of AP2, the NS Pro shafts used 105T allowed me to win ball speed and comfort as they are lighter than the Project X Flighted 5.0 that I use on my x22 tour also carry about 15 more yards. But I'd like to find a somewhat lower trajectory clubs.

When fitting with Trackman, I noted the following values for my swing:

6-iron:

Speed: 85 mph
21/22 ° Vertical Launch
Spinrate: 6500
Carry: 145 yards
I have a doubt about the spinrate measured at 7000 on my Titleist fitting.

Driver:

Speed: 91 mph
11 ° Vertical Launch
Spinrate: 3100
Carry: 220 yards

I understand that you advise me on NS Pro 105T Stiff but the first NS Pro 970 can be an option?

Apparently, I have a positive angle of attack on my swing with the irons which handicaps my acrry and also provides high trajectories. Would you advise me to go for my pro to try to fix this problem before buying a new xet of irons ?
