I’ve been working a bit on my sweeping technique lately but have been having a hard time finding one that’s usable in both directions and which dovetails with my regular RDT picking technique. In particular certain sweep paths will change the pick point, which creates a problem when I then move back to alternate picking. The search space seems quite large, since there are examples of great sweepers that use only wrist, and those that use wrist+elbow, which essentially means you can sweep in any motion path you can imagine.
Since the RDT picking technique essentially fixes the pick orientation, does it also dictate the direction I should sweep? What are the rules here?
