Everythign in the end comes down to the game and the history of design of the teams you will be opposing at regional events. For team 1368 i suggest analyzing the game as well as the opponents then decide what you want to do, also as for belt drives the friction force of the belt on the pulley is less than the force put out by a pushing robot, so if you get hit and pushed, you WILL get pushed and your belt system WILL slip on the pullies. Also i suggest a simple rocker drive system with powered wheels in the center powered by CHAINS with 2 omnies on at the sides of the robot, this configuration works best.
With Splined(Toothed) pulleys,from brecoflex, you will not get pushed from the front and with the correct belt profile(V shaped profile in the center, TK10-K13) your belts will never slip sideways, this mixed with the long contact patch basically means you won't get pushed sideways either. the only pushing weakness of treads is due to your gearbox, if you don't have enough torque you will get pushed front to back or if the opponent catches a corner of your robot you can be spun.
