Yeha, I have my dynafits cranked as high as they will go. In fact, on terrain where a fall would be deadly, I actually lock the front of the binding into touring mode so that I basically can't release unless I really torque the thing. i suppose a busted knee is better than having a ski pop off on a horribly steep slope.
BTW, how does it take 10 minutes to get into dynafits? They certainly aren't as fast as heavier bindings, but it never really takes me more than 30 or 40 seconds even if they are being a pain in the ass.
