I play the 913fd 15 degree fairway wth a ProForce V2 76g shaft.  I ended up going with the fd as oposed to the f due to the lower launch angele and the deeper face.  I tend to primarily hit this off the tee when the driver is too long so the fd was the best fit for the primary use of the club.  That being said, I do end up using the club off the deck at times but I still hit it about 20-30 yards longer than my 18 degree hybrid.  Part of this may be the fact that I tend to have a steeper attack angle with my swing and, while the ball flight is lower than the f, the fd still gets adequate distance.  I use a tip-stiff shaft to account for the turf interaction on the fairway shots.  I have found that I can alter the ball flight but changing the ball position in my setup and my swingpath.  It may be worth spending some time on the range to figure out if tweaking either of these items has an impact on your ball trajectory.
