I like MIJ drums, & a small group of musicians on the VDF like them, but I hope you didn't bet any money on the statement that, .."professionals are increasingly using them to tour & record". (there used to be a legal definition of a professional as one who made a living for 2 years at a stated profession). ..so this would not be the VDF weekend warrior or the occasional gigster who reports on forums about his MIJ set.
I think a professional who toured w/ an MIJ set would be as rare as an Indy driver who raced w/ a YUGO.
Questlove is the only Pro I've seen who used a vintage MIJ set (Yamaha 70's ?), (though recently he switched to a Ludwig kit).
