I recently got a used Nike Sumo 2 Stiff for a steal of a price.(Sent it back and got a brand new one) Any how I played with it for awhile, didn't like it, liked it....Tried other drivers.... you know how it goes with your driver sometimes. None the less I am back on it. I also never used a stiff shaft before. I was told that I have a high swingspeed by friends. I never been fitted. The sumo 2 hits so high of a trajectory you lose distance I think. I was wondering what kind of shaft could I put it in too make it a lot lower trajectory. Anyone who has seen these thing hit know what I am talking about.
