Replying to Advice please. Atomic backland 117 binding mounting position?

Just picked up a pair of atomic backland 117 in 179. I got a deal that I could not refuse I’m hoping to use them for all mountain /off trail/ pow/crud/groomers/etc
before I have the bindings mounted Ive been reading people are mounting them +3 foward from recommendation. The standard seems to far back. What do you guys think. ? Ive been out of the game way to long
