jason...you're 195lbs and run your DIN at 7 and you dont know why you keep popping out of your bindings. really?
Yeah I've kinda of got to agree with this guy. I'm 6'1 at 170 and I ride my skis at a 10. It depends on the binding ad well though. I used to game some sth 12s that I had to ride at 12 and I eventually ruined the spring and had to purchase new ones, now with marker jesters and fks140s I am able to ride my bindings at 9-10 and they stay on perfectly fine.
It sucks to have to go purchase new bindings when you think the ones you have now should work fine but... it's just part of the game. As you improve your gear will improve with you.
Either drop into a shop and ask them or crank the dins yourself.
Warning: Lots of shops can't change DINs due to liability reasons but it's easy to change yourself
