Zero, I think the problem is you're not actually playing keys with a 4 or 5 piece jazz group. The band I usually play with is 5 piece with sax and guitar. Many times I will just use the shells as Mac described with the left hand only and rest the right during the sax or guitar solos. I've learned (finally!)less is more and won't play anything on some tunes for part of a chorus of even a complete chorus to give the other soloist some space to develop something. Two of the sax players I work with will call for just bass and drums to start off some of their solos then the piano and/or guitar will come in later. All of this of course depends on the tune and what I'm hearing at the time. If the guitarist is doing some cool Wes Montgomery type chord comps behind the lead I'll back way off on the keys and do the left hand shells. He does the same if I'm doing the comping. Watch some jazz videos closely, you'll see that happening a lot.
