G day Calvin, if you have a specific driver shaft in mind just go to their website and check the trim code; some do some don't.
Just bare in mind fairway heads are usually heavier than driver heads so the extra weight can effect the flex rating by a point or two.
My advice would be FW specific but using driver shafts is more common than you might think.
Good luck with whatever you choose.
Fuji Fuel is a good start, numerous weights, not to exy to experiment with, very stable and no trim code required, v good all round shaft :)
