I'll second that. Whatever sounds right. I don't have 2.0, just DFHS, but I'll usually try to get them at a decent volume as a group, and if a certain tom seems to jump out, or if one seems buried a bit, I'll adjust to compensate. They don't all have to be perfectly the same, just as long as none are sticking too far out front and none are getting stepped on by the others. The toms are kinda like a little squad that needs to work as a team. It's best when they work together. Don't let any of them gang up on any others, and don't let any of them get too cocky and independent.
