In 2003 we used 4L v belts for the drive. They worked OK but since then we have gone back to #35 chain. V belts will slip when torque goes above a certain threshold. This can be a good thing. Locking up a drive is bad. Something has to give or the motors are going to fail. We used timing belts for our arm in 2004 and 2005. If we have to use an arm again we will probably try something different. Timing belts probably would have been good as a drive for the shooter wheel this year. We used direct drive for the shooter and chose the wheel to match our velocity requirements. Less points of failure and eliminates some friction losses. The timing belt pulleys of the size needed for 6 wheel drive are expensive compared to IFI's aluminum sprockets.
