I won't use a 3 wood in a tournament. The risk, for me, out weighs the reward. My miss with a fw wood has a flight path that is similar to a frisbie.
I hook the ever living shit out of my current 3w. I don't know what it is. I think I swing it on a very shallow plane for some reason....can't do it. Hopefully I can work it out with a 4w.
