Mattyv I use FST90 steel shafts in my hybrids.
Thread necro alert!!!!!!!
I'm a fan of the FST115 (trimmed stiff) shafts in my irons. I've played them in hybrids and they feel fine but just a tad heavy. I'm thinking about trying out the FST90 in some hybrids but they don't offer them in stiff. I'm thinking of trimming them in regular plus an inch. How's this sound?
P.S. I think I've asked this before. If so, ignore that one. 🙂
