With today's equipment, anything super-short will kill us.
I would say reverse-block, but you very rarely see anyone lay it down on purpose anymore. What you *do* see is a flat shot where the track area gets burned down and then it looks like a reverse block.
Actually, Cheetah is worse for me than reverse block simply because I used to bowl in a house that would do the flat oil/burned out track thing and I got a lot of practice on it. Next to that is the U.S. Open pattern.
