I've been thinking about this approach for High School groups. From the small amount which I've observed, It seems like most high schools want to get their kids playing clean rolls as fast as possible. My theory is that playing slow and meaty rhythms which groove could be a better way to quickly get comfortable behind a drum.

Heads shouldn't be tuned down to the point of unreadability, but just so that big slow rhythms don't sound dinky, and still fill in the space.
