I had a couple of AF types train me, we use a 500' bubble and 3000' agl hard deck. Call if you lose sight, knock it off under certain conditions, I'm guessing along the lines that most ACM IP's teach. The pictures are from an air show I flew, so things were pretty tame, mainly became a vertical scissors.
Tracom rules were 500' bubble and 10,000' hard deck (or 5k above highest cloud deck IICR), though 3k is probably more than enough to recover an OCF yak I'd imagine. There are actually a whole couple of pages worth of training rules that you must know, but yeah the big areas are lost sight, blind/sun, and ROE for the flats.
