we too ordered some 2"bore 24"stroke cylinders, and derived empirically that we are able to fire them every fifteen seconds (just one) without hurting the air level. two is a different story, i doubt that you would be able to fire them with much power.

also, you mentioned retracting at the end of the match. remember that you don't have to return to starting configuration at the end of the match. i don't know what you have in mind, but if you're expanding your robot by 2' on each side at the beginning, you don't have to go back at the end.

good luck!
