Generally I do not roll the overheads off much above 100 or so ..of course it depends upon the type a sound you are striving for. I would also suggest an experiment for you. Once you get past fixing any problems that the drums have ( rattles, over ringing etc) record them and route them into a sub group and apply your eq and compression to the kit as a whole on that sub channel. With the drum kits I've mixed I'm finding that once I get an even balance on the kit (snare generally 3 db hotter than everything else)and if I do only minimal (if any) eq'ing to the individual drums and treat the kit as one instrument I'm getting some very good results. ...and if I'm not completely satisfied with the sound I then go to the individual tracks do whatever to get what I'm looking for.
