Those pearl masters bass drums sound sweet! But I would go with the Tama's, every B/B kit i have heard or had the chance to play on was awesome. Definitely will be my next kit that i buy. The mounts are solid, maybe someone did not set theirs up right? I have not really come across any that were wobbly, they all will move a little bit but nothing out of the ordinary.
