OK...I don't think it's the material that u make the board with. I think the biggest problem is the highly recomended 'quick release' mechanizm. Last year, my team had our board hooked on the bot with nuts and bolts. What made it worse was that we forgot the wrench that fit the nuts. As for the material, we went with lexan last year. For testing, we use a non-permanent wood board that will be placed on a more stable material when we want to make the design final. The over all advice, DON'T USE NUTS AND BOLTS FOR YOUR BOARD!
