...System with Mike Michalkow or Learn? and Master Drums with Dann Sherrill? Both systems have gotten pretty good reviews from what I have seen. The Drumming System is a bit more expensive than the other. However, it is mentioned in the description for The Drumming System that it teaches all various kinds of time signatures from 5/4 to 7/8 to 9/8 beats. Does the Learn and Master Drums series also teach these kind of time signatures within the material or is that only found in The Drumming System? Please tell me which one of these is better and whether or not the extra money is indicative of a better system.
