There was something about a Q&A post in 2011 that implied a "competition-only" battery, and I wasn't the only one who got that impression. Hence the 'were' in my statement. I didn't pay attention to 2012 pneumatic Q&A since we didn't use pneumatics last year.

My point is that planning and depending upon a large quantity of air is just as bad planning and depending solely upon a constantly-stressed battery. There's no free lunch here. All it takes is for a question similar to the one from 2011 to be asked, and receive a similar response, for the whole design to go up in magic smoke.
