Until the pandemic, Josh Freese was in the chair. Probably cheaper to have someone new than to pay enough to cover Vinnie or to pay for Josh to fly between gigs to fill in for other drummers.
Yes, absolutely. Dave Krusen's work on Ten was good, Dave put a less refined version to emulate it. I thought Jack Irons was a better fit but Matt Cameron is just a better all around drummer.
I did it by weight. I have a 16” 2002 thin crash as a top and a power crash as a bottom. I know the range of weights for those two models and paired from there. They’re about the same weight as many 14” hi hat sets.
