Replying to JJ 2.0 mounting position?

Just ordered a pair, they will be my everyday ski out west. Wondering where people who have ridden jjs like to mount them? Also, does the slight change in design mean that moving further forward won't be such an issue (I read in other threads that going any further than 2.5 back was a bad idea)? Right now I'm thinking about putting them at 3 back from true center but Im honestly not sure at all... Any help is appreciated!!
