Replying to I think my DIN setting is too high.

Right now im skiing 07 public enemies with rossi axial 2 binders. i weight 180 lbs and am 6' 3". I consider my self a intermediate skier. when i took my skis to get mounted they put the binders at a DIN of 8. I dont remember what the Din was on my volkls w/ marker bindings were but im pretty sure that they were lower. When i took them out this weekend i fell a couple times and they never came off. Maybe i got this all wrong and its nothing but i wanna play it safe because i dont wanna fuck up my knees. any help would be awesome.

Thanks!
