my guess is that you're either recording with the kick mic way out in front of the kick, or you're adding a ton more click than you need to.
unless you're using your kick mic as a room mic,the bleed from the snare shouldn't be a problem at all. if you are using the mic as a room mic, yeah you'll have to get another mic if you want to add attack without bringing up too much snare.
how are you micing the kick?
