I think it may really seperate those with good cardio, and those without.

We've sparred 3 minute rounds in my gym quite a bit, and then a week or so leading up to a fight....then bring it down to 2 minutes. I guess we won't be doing that any more, or atleast I won't. Not sure.

This again poses another problem for me in sparring with so many new members. Whereas they should be training and aiming for 2 min rounds pre comp....fighting in open class am going to be shooting for 3 min rounds.

I still have mixed feelings on it. Just got to 4x2. Suppose will know better after first real fight at 3x3.
