For the Cheetah, I would suggest not getting too locked into how the pattern is "supposed to play" It's certainly worth putting a couple of balls in practice along the edge to see what kind of reaction you get but don't be afraid to look elsewhere.
As for surface/drill/ball there isn't necessarily one answer to this other than the standard answer for most of the PBA patterns: weaker pin positions (in either direction). An angular ball can work well once the pattern has broken up a bit, but they can be tough to control on the fresh, even tougher with as long a backend as the Cheetah.
My main balls for the Cheetah are: Tropical storm, 6" pin high, Jolt solid 2" pin medium, Classic zone 5.5" pin high.
Surface will depend on your game, if you have a lot of rotation and can't reduce it then you might need to add surface to burn off some energy while on the wet. If you have the stronger drills, it'll be really tough to control on th backend, so I'd steer clear of those.
