Has anyone thought of it from this angle: what about training normal athletes and what is best for them as opposed to guys competing in the highest level? I don't think there is a right or wrong answer, but I bring it up because we always refer to guys who are training at the highest level as an example of what we should or shouldn't do as grapplers, but some times their students have a success rate in local tournaments that is no better or worse than some schools that have lesser known instructors. A little off topic of gi vs no gi, but food for thought.
