To make more room available for the bottom end of the kick I set HP filter sweeps as well as gain reduction in FL Studio to duck with a second muted kick drum (using a peak and forumla controller combo), but something I've started doing recently is triggering the transients a few ms BEFORE the kick drum and with a longer attack. This keeps the side chain compression smoothe as silk and less noticable, but still gives my kick a nice amount of room to really punch through the mix. At the same time I link the gain on reverb sends to the same peak controller so that they also duck in time with the kick. If you listen carefully it has that acid techno kinda thing going (far more subtly of course), but on all instruments using reverb, not just the kick (which I keep mostly dry anyway).
