D,
That may be true of the folks in the open run w/large rosters, don't know...everyone has there own style. I think those folks out on the West coast US can tweak some fast bases from what I hear and see on you tube, not to say other leagues don't...they all seem fast to me
I am still experimenting and my bases change frequently along with my style. I try and get best practices from everyone I play and ask an LOT of questions to Geno H, Joel P, Mike Pratt, Don Smith, RPD and many more.
I have found a lot of these GREAT players have different styles and theories. That's what makes it fun. There is no one right way.
My style is still evolving both on "O" and "D"...right now, I just play "lost in space"

but love the challenge to get better...
