Replying to 4frnt VCT

Right.. i'm 5'9 and a whopping 140 pounds (attempting to bulk up).. I am getting a pair of 4frnt VCT in a 182. My question is.. who has skied them.. and where did you mount.. I am going to be using them like 60% Backcountry Freestyle and jibing about, 30% Lines and about 10% Groomers (getting from A tp B). I am thinking due to the fact that these are 7cm above my head, I can get away with a relatively far forward mounting point. Recommended is -6 from true, which is WAY to far back for me. I was thinking of about -1.5 from true.. Any input?
