at the start of this season I picked up a technine team series board for my brother who is a beginner. the board was used on mellow green trails for 5 days. so last night I was waxing both mine & his board and I noticed that his board has no camber!(the camber was there when I recieved it) his board is flat between the bindings just like my horrorscope. i've had boards that didn't lose camber after 1-2 seasons of hard abuse. can the board still be ridden or is it done? does it mean the board is defective or just a total cheap piece of shit?
