Yes, I've been using folders all along. I don't know why I didn't think of using it for drums. I think it might be because I have my overheads in a folder, so my brain probably didn't compute the possibility of putting a folder in another folder.
I like that option better. Greg's suggestion of un-clicking the "master/parent send" works, too. The only thing about that is that I'm used to putting the MIX control in my reverb all the way too WET always. With the un-clicking "master/parent send" method, I think I'd have to put the MIX at 50/50. I might be wrong about that though, because I didn't try it yet.
