It appears he has them reversed and is smacking a cymbal in the shadows that is cutting off the view.
IIRC, Mitch used 7As in those days. Long sticks, but a bit slim for my tastes even in my 5B and 2B days. Anything slimer and shorter than a 1S is a toothpick to me now, but I do have a sweet pair of Trueline Mikel Thomas models that are probably based on 5As but have that Truelie acorn shaped grip.
Thinkin about messin with some 1S's though. gotta run to church, be back afterwhile
