KCee I think wedge shafts can work, even for full shots, but they are not all created equally. The ~ 8i shafts in a wedge work well IMO unless your wedge is.a crazy high head weight vs. your 8i. If it's softepped ~ x2-3 then IMO full shots are still doable/fine. I don't like to step on wedges anyway unless I gotta get up over a tree or something like that, otherwise it's more of 3/4 seing, etc.
FYI re the HiFlight Wishon wedge shaft.....it is an untipped Apollo Shadow steel shaft....yes untipped....that's why they are ballooning!
Another option is to do what FST does .... There KBS Hi Rev wedge shaft in S flex is a KBS Tour X flex 8i shaft.....so soft stepped x2-3 to get to same/similar flex from the butt, yet a slightly softer tip then a straight in S flex KBS Tour shaft, so going to be roughly the same cut weight!
