Judoka have adapt experience for years and years already to wrestling, shunyata. Since then, we have also seen judoka in mma and I still don't see any indication of why they need to adapt to nogi, at judo. They do just fine there from observation. It sounds like you would say wrestling has to allow subs.(?)
It's too easy to adapt to nogi. I think many are trying to throw w/o gi before they even learn to thro in gi and that's an issue.
But, I understand that you think it would help memberships if judo offered nogi. Fair enuff.
I still think Judo clubs are not open at the idea of nogi training.
