Most assym spins are dogs on a dead run, they're more of a reaching and broad-reaching sail. So the "jibe-broach" really isn't a concern to you. It's the "involuntarily head up and broach broadside" you're concerned about.
To avoid it, ease the main first, it'll help you bear off and put the wind more behind you, which should steady you up..
If that doesn't work, then the boat's going to head up on its own, so let both sheets out and just hang on. It helps to cross-sheet the spin sheet to the windward winch, so no one has to dive to leeward to ease or trim, which you don't want.
I'm not a big fan of the assym spins, am more old school and like the symmetical ones with the pole. Clearly I'm in the minority here...
