Ricky Welch is one of the best shooters in the world, and he shoots 3-under. I know several excellent shots that shoot 3-under. If it works for you, don't worry about what G. Fred or anyone else says--when one "expert" says "this is the way you have to do it", you can usually find another that will say just the opposite. I tend to listen more to the ones that say "this is what works for me" rather than "this is the way you should do it, period".

Good luck,

Chad
