Very similar to spinning off actually, in fact i think their the same except i feel vulnerable when i spin, as if i get hit a flash knockdown may occur ya no.
Ok Im an orthodox.
If he advances ery quickly, i initiate a clinch quickly,Draw him close and then move my left (rear foot) clockwise, turning the opponent in the process, then shoving him off me, he's at the ropes and im mid ring...Hope i explained that ok.

And i get what u mean about the leaning/support thing it does work i think, but wouldn be incorparated with my style at all.

Nigel Benn used to utilise the ropes a lot to power punch, leaning and almost catapulting himself for added momentum. Dangerous tactic but may be worth the risk if u can hook well.
