No the pivot 14s are not bulletproof. Neither are the pivot 18s for that matter. Jesters are a good binding. Even griffons
IMO the best bindings for park are STH2 13s or 16s. 13s if you are a little dude, 16s if you are a bigger dude. One of the most durable and most adjustable bindings. Brakes do not brake easy, but are still easy to replace and cheap (unlike pivot/fks). Plus the rubber stomp pads are good for shock absorption
