The first thing to ask yourself is what are you trying to accomplish by using gates? First and foremost, what does the kist sound like as a whole without them? It is after all, one instrument and generally should be treated as such in the mix.
If I'm looking for punch and clarity, especially in the kick, the first thing I will generally do is flip the polarity on the kick track opposite the rest of the mics on the kit. 99% of the time, for me at least, I see a marked improvement, depending of course on the kit, style, drummer mic placement etc. etc. Sometimes the kick and snare will both jump right out at me as soon as I flip the polarity. YMMV
Then after working a little eq and balance, on the kit and in the mix as a whole, I might examine whether I want to use any gating or not. I have been doing a lot of live recording on location in clubs lately, so I have actually been using a bit more gating since I'm encountering a type of bleed you don't normally get recording an isolated drum kit in a booth
Anyway, when it comes to bleed and gating, you just have to give it an honest listen and decide whether the bleed you're getting is:
A.) Detrimental to
B.)Neutral to
C.)Benifical to
the sound of the overall mix. Gating bleed "just because it's there" has never made any sense to me.
and yes, the waves gates suck
good luck!
