Swandog7For what he needs yes. Like the top 6-8 bindings used for park are not much different. They hold very similarly, some better than others based on price and some quality of heel/design. You can't feel almost any difference between say the attack 13 and Marker griffons. They for sure aren't as different as skis. You can't really make a bad binding choice between most "park oriented" bindings other than squires
No. On a basic level I can see what you are saying, all bindings are made to release at their set DIN, so in that you are correct, but there are differences between them (elasticity, stand height, ramp angle, durability, etc.). The differences can make certain bindings feel very different, just look at the sth vs z toe or peak vs attack toes and how different they all feel.
Anyone could most certainly make a bad binding choice if they end up with something like pivot 18's but should have their DIN set lower than 8.
