A set of exercises I improvised on my leg at the start of a rehearsal yesterday— and this would actually be good as part of a warmup. These are 5 stroke rolls in single strokes, in a 32nd note rhythm, accented a couple of different ways. It's very straightforward, and once you can play a single stroke 5 fast starting with your right or left hand, you should be able to knock this page down quickly.
If you can do one of these you can basically do all of them, so there's little point in lingering on any one exercise. You should be able to do everything you need to do with this page within 10-15 minutes, or within 2-5 minutes as part of a warmup. This would be a good page to play with brushes.
