I ended up getting Burton Lexa bindings for my new Roxi board- the discs on the bindings support either a 3 or 4 hole pattern.  The front binding went on fine but for some reason on the back binding something is off slightly so only 3 of the 4 holes line up.  So my question is if I go with the back binding only having 3 of the 4 screws in it is this a big deal? I'm thinking no but wanted to double check just in case...

Thanks

i dont recommend it at all. if the plate is aluminum, it'll probably last a day or 2, but its going to put alot of stress on the bindings and the board on whichever side you left the screw out. ive never tried to turn the binding plate for a 4 bolt to fit a 4 bolt board with a 3 screw set up..if that makes sense. id call the place you got them from and get a new binding plate before you ride it, seriously. i rode a mountain with an aluminum base plate for a day when i lost a screw on the mountain and it did ok, but i make more toe side turns so i put the 2 screws on my heelside because thats where alot of the resistance was and nothing bad happened to me, but when i tried that with a plastic base plate, the thing cracked 2nd run.  isnt it still early enough to return it before the snow falls?
besides, you just got a killer board, id hate to see you harm that thing before you even break it in.

When you say off to the side you mean like at an angle?  Cuz if thats wat it does and it gpes in just a lil. Then i thing its a stripped screw or something..... 
Goin to the shop is a good idea
