ok so i just got some 177 bangs with px12's and personally i love them,
super poppy and fun on rails, so light compared to my older skis that i spin them like nothing,
i think there stiffer than i expected but butter amazing, they definitely hold their own outside of the park (obviously not gonna beat a stiffer ski) personally i have no problems landing switch. overall they are super fun and great if your looking for a park only ski
as for top sheet chipping, its only the top sheet wont effect riding therefore who cares
