Just to clear up the speed hole issue;
When some one talks about speed holes, all they mean 99% of the time are holes drilled in the bot to make the weight limit. They got the term speed holes from a Simpsons episode, and because getting rid of extra(dead) structual wieght can only make you faster. Besides, when some one asks why you're bot looks like a macoroni strainer, its cooler to reply 'Oh, those are the speed holes' then 'Oh, we were 3 pounds overwieght...'
So when you see a bot that looks like swiss cheese, it really means the bot iss really really fast
