Lead-Dubs Chuggada is an exercise inspired by the 5/8 Chuggada which runs through three rudiments that all have [roughly] the same lead-hand breakdown: Swiss triplet, off-hand Swiss w/ kick, and hertas. The idea is that most of the brain-work happens with the off-hand, although there is slight variation in timing and stick height with the double-beats on the lead hand as well.
