My $0.02. Dave Weckl is an awesome drummer. One of my favorites. After listening to him for many years (but never seeing him live), it was great to see him live in a clinic. I wrote up a review here ... http://www.vdrums.com/forum/showthre...ighlight=weckl
Having tried to pick up traditional grip unsuccessfully for many years (probably like 15+ years), the insights on ergonomics he provided at the clinic finally got me over a hump.
I'll always remember that clinic. His playing and drums sounded awesome.
