It definately sounds like IR will be more important next year (or so was the plan). I don't necessarily agree that there is any problem with it this year with interference or anything else. It all depends, obviously, on the design of the housing mechanism of the sensor, correctly limiting its input and reducing reflection error ... but the IR portion of our code has worked every single time at 2 different regionals (we use a specific pulse width plus first is monitoring for stray ir signals, so that can't really be a problem ... and dealing with reflections is part of the game/design challenge ... remember, it ain't supposed to be easy!).
