Gotta echo most of what's been said. My current fave kick is a Keystone 16x20, tuned for punch and tone. It cuts above a low bass, so it's easily heard in the mix. But it also has a nice thump and punch, so it sounds like a 22 or even a tightish 24". Not sure if it's the shell (oak & maple) or the size, or the heads (clear EMAD, Ludwig reso, no port no padding.) but it just sounds great. I have a Legacy kick that's 14x20 and it also has a great punch and cuts through the mix.
Recorded, they have a surprising amoujnt of low end, and playing wise, to me they feel better than a larger drum. Also, they fit in the Smart car easier than a 16x26"!
