You got my vote for RA2 Wizard. Always and forever.

Me and FB made a few omnidirectional bots back in the day, and the main problem I've seen is that the sideways-facing wheels slow the bot down too much. You need to put a lot more weight into the drive, and you don't even go any faster for it--you go slower. The only kind of bot I've seen that's real effective with that drive setup is sit and spinners.
Hmm-Use Snapper II's rather than Snapper 2's for the overlapping.
