Jits and Judo player here.
I think OP means suwari waza, but I don't get what his troubles are, in fact I think he's asking for more trouble.
OP: If you keep rolling and taking backs from your knees, your partners will pull guard.
Hi yes I meant suwari waza. Sorry for my ignorance. What are the principles of this posture?
Edited to say. By principles I mean weight distribution when one knee is up, what part of the foot is touching the floor, any little tips like that.
