Just to add a little complexity to Gord's excellent advice.

It's worth checking the shaft options too as you might find 3 or 4 different regular flex shafts available. Depending on how the shaft is designed it's possible to vary the pivot point so that the launch angle varies for the same loft. If you go for a higher loft (say 10.5 deg) then just check that it's not mated with a shaft for a high launch angle. You might find that this combination causes the ball to balloon of the face losing considerable distance.
