This is a killer exercise to get more control over both triplets, rests and alternating hands. Some potent "health food" for the head and hands. Thanks for putting it up. See ya next week.
I'm not sure my drumming qualifies for the "chops" level, but I give credit to Freddy Gruber, Bruce Becker, Jim Chapin - Moeller Technique,, Joe Morello via @rickdior, his 'Hand Technique' videos are awesome, and Gordy Knudsen of the Steve Miller Band, his videos on the open/close technique are very well done & demonstrate the bio-mechanics excellently.
Excellent! It sounds like your study of hands has quite the lineage and breadth of influence. Thank you for the detailed comment, it's nice to know what everyone is up to out there.
