I got to add to this because I just noticed more and more discraft creeping into my bag. They pretty much have a stranglehold on my midrange stuff now. My cobra/rocs have been replaced by buzz/MRV/breeze. The discraft stuff just seems to hold a tight line better, which is what I need since I play a tight, wooded course.
my putters are still split, I use a challenger for overstable approaches but carry two avair xs for understable, stable approaches. One 15, which is awesome for finesse approaches and one 4x, both are beat to hell. My putter right now is a banger, which has been nailing putts for me. I do have the 5 wizard deal coming in the mail though so it might be getting replaced.
All my drivers except one are Innova though, I got a wraith, two orcs, sidewinder, leopard, and gazelle. The one discraft is a Z Avenger which, for me, is the best headwind driver I have tried.
As for Gateway, except for an element x I found I really haven't giving them much of a try. I will eventually though.
