I guess theoretically it depends on your swing, and there are other things to take into account other than spin rate.  but I find the kal'li stiff shaft to provide the most powerful and boring shots into the wind of any shaft I have ever seen.  This past weekend I hit two drives into the wind that were farther than  I could have imagined. the second one was in the rough and we couldn't find it because it was 50 yards further up.  Driver, lob wedge into the tough finishing hole at the club, into a 15 mph wind.  I'm 54 with a moderate swing speed (105mph or so).  I love this shaft.  It seems that if I hit it right into the wind it goes just as far as it goes without wind. --Jerry

I have the 910 D3 8.5 degree with the Ahina S flex. If you look up the specs for the Diamana shafts; which is the shaft I have in most of my woods/metals;  they traditionally indicate a lower launch pattern. Given that; your position over the ball and  the plane of your swing will influence or dictate the launch pattern.

The absolute best method to determine this is to go to a fitting with a certified Titleist fitter, and with their computerized equipment it will show your characteristics with each of the offered shafts.

Hope this helps

if you scroll down a little bit it looks like the rip 80 has the lowest spin and launch for any non-upcharge shaft. Its followed by the rip 70 and then the titeist ahina.
