What degrees should I set my snowboard bindings too?

Since your riding park you'll want to ride with a duck stance. Jump up in the air with both feet and land on your board and see how your feet naturally land. Try to put that stance on your board. You'll probably want the most natural feel possible. Thats why I ride with my bindings almost straight (-7 and +7). So try to work around that and see how it goes.

Start with 15/-15, then try 10/-10, then adjust to your preference. I prefer to keep my settings symmetrical for equal balance and comfort when landing switch.

It's best to go duck. If you haven't got your settings to a duck stance already you may want to play with the settings to what feels comfortable to you. You can always adjust it again later. I ride with 15 in the front and -13 at the back.

you jus want bother to be angled out. mine is -15,15. and im comfortable with that. but it should be what your most comfortable with, but you do want bother to be angled outward just incase you get stuck on the backside

IF U R A PARK RAT, U WANT TO GET A DUCK SET UP ON YOUR BOARD, WHICH MEANS EVEN ANGLE ON BOTH SIDES, LIKE 10,-10. OR 0-0. U HAVE TO FIND A MOST COMFORTABLE ANGLE FOR YOURSELF, EVERYBODY GOT THEIR OWN SET-UPS AND IT FEELS DIFFERENT WITH A DIFFERENT BOARD AND BINDINGS, SO PLAY WITH IT, SEE HOW IT FEELS, AND MAYBE DO SOME ADJUSTMENTS...
