they don't seem as durable as some of the mervin boards i've tried, but those boards seem indestructible (my rider's choice has eaten SO many rocks and stumps but only a few light scratches to show for it) so it's not really a fair comparison.
i do a lot of glades riding too, so conditions vary too much to really determine whether the board durability sucks or if i just hit some really nasty shit that day.
anyway, i'd think back on how your day went. there was one time where a skier collided into me and i thought nothing of it (no one got hurt). then later in my room i noticed that part of my topsheet was sheared off on the nose. so, yeah. you never know man. those collisions that don't seem like much can do some damage to your board.
