Replying to K2 recoil binding placement

Quick question. I have a pair of used 2012 k2 recoil 169cm skis (i hear they really come out to 172cm) coming this week with only like 15 days skiing on them. I have a pair of FKS 140 95mm im going to put on. Im 5'11 and i want these to be 75% all mountain and 25% park. Where should i mount the bindings at? I obviously don't want them true center bc they are going to be an all around ski. Should i go -1 back from center ? -1.5 back for center? -2 back from center? what do you all think, help a brotha out!
