$30 speed hand: what's my move?

[Soulman]

This was a $30 speed Monster qualifier (yeah yeah, bring the hate; 95% goes to the prize pool and the competition is sooooft), about 20 left of 60, top 6 gets paid. For me, anything below top 3 isn't too important.

I hadn't made any big moves, pushed a few times and called a push with AA. Limper limps way too much, but pretty much always folds when facing a raise. CO is the aggressive big stack, doubling on a suckout then stealing blinds here and there to gain his current size. Nothing really out of line though, all of his pushes are from LP.

What's my move?
