Amusing hand from bidding practice

Last night, I was practicing bidding with my partner Garth. Garth and I are playing several upcoming tournaments, and we have a very complicated bidding system, so we want our agreements to be in tip-top shape for our first big test-- Gatlinburg in just over a week. We've been practicing several hours a week, and getting better every time.

This hand came up as the last one of the session.


I was very amused to notice that game was most likely on in all five strains - these hands will probably make 3NT, 4H, 4S, 5C, and 5D! I've been experimenting with the E-W hands a bit, trying to see if I can make a full hand where N-S can make game in all five strains but can't make slam in any of them. I've come close, but it seems like 6C by South is always making. Can you come up with a better construction than I did?
