Sick-Stroke Roll Schops is a chops builder or just a good way to get pretty warm pretty quick. It has really basic construction (other than the 5-bar tag) so you can just dive right in.
If this website had a theme, it would be juxtaposing different interpretations of rudiments. The rationale behind this practice is usually given as "building understanding and control of the space between notes", but in the context of this exercise, it's also just a good way to warm up the muscles you'll need. It's common to play a bunch of kinda fast rolls to get the blood flowing... now you can play a bunch of fast rolls with some slightly slower double-beats thrown in there, as well as accents and taps... and you have to switch between them... a lot.
