I'm gonna say try to play striking mod like lenshu3ng more often, because on that kind of mod you're not depending on a grab. Also try to learn how to "Crabbing", it's pretty helping when you're separated from your opponent. Use relax wisely, usually i use them when I want to fix my position quickly like preaparing a comeback.
But I'm gonna say, no grab aikido usually just for fun or to challange yourself, but it's pretty fun if you're playing againts a no grab aikido player too and you're gonna feels like playing lenshu3ng in a small square dojo.
Also, try to play with xbcz, he is always playing no grab in quick aikido.

Anyway, I saw you entering public6 before but quitting. Actually I was playing no grab ABD there.
