Curiosity, are all 6 of your wheels in contact with the floor, or is it a rocker?

Thanks Eric. The weight distribution might still need a little work, but it's not all that bad. With more of the Pneumatic system in place and the pound and a half of Brass fittings we had to add onto the compressor and tanks the weight has shifted a bit farther forward than expected. Once the claw, arms, arm motors, and Mini-Bot system are in place it should come in somewhere around 50/50, though I'm hoping for a split closer to 45/55 or even more rear biased if possible.
Technically, the drive is a rocker, though the rock isn't much. The Center wheel is offset approximately 1/8" lower than the outer two wheels, so it has a little bit of rock but it's barely noticeable on carpet. I'm really not a fan of some of the higher offset rockers we've used in the past, they almost seemed to rock too much, but I think we've nailed this one.
Nick and I had a chance to beat on the chassis last Saturday and were thoroughly impressed with it's speed, agility and stability. Hopefully some time this week he and I will have a chance to put it through some quantitative testing to get a real feel for how it'll hold up in competition.
