They don't all wear Dexters. I'd have to look at the last couple of tapes, but I know that there was at least one pair of ABS's worn (Wiseman, I think), and unless he's changed shoes, Chris Barns wears Linds. Both Norm Duke and Brian Voss wear somethig different yet.
Yes, they could describe the drillings, but most of the time, what works for them will not even come close to getting the same reaction in the hands of most amateurs.
