blew a bag!

i blew a bag 2day on the way home from a friends house, the first day i got it out of the shop 2. it was great lol, i drug it for a good 40 feet. its back in the shop now i gotta pick it up in a few hours. the problem was, he didnt cut the cup spring cup enough and it rubbed. how many bags have you gone threw since youve been on air?
