Well I have two things to say, and I'll keep em short. First off, you already bought the bindings, so I don't know if anything you ask us will really help you, except the screwdriver thing which is definately true.
Secondly you are most likely in for an often occurance of prereleases. Even with my DIN turned up they still come off, and like the other guy said it happens a lot on fakie landings. I also have problems landing in anything thats deeper than a few inches. I'd crank the DIN up higher but then I run the risk of it not releasing when I need it to. Good luck because you're probably going to need it.
