If the hats and crashes are
ouch then they are probably way too loud. Hats and crashes cut through amazingly well and can be very low in the mix and yet still very audible.
I have played in a band where everything was miked up to blazes except the hats and the OHeads were not yet the sound engineer used to tell me he could still hear them as clearly as anything.
(when I used nylon tipped sticks that is)
You can HPF the hats and the crashes and even apply some nice HF shelving boost to them as well but then pull them way down in level and they will still be there.
