Replying to Binding mount help

Hey NS, so a while back I bought a pair of surface one lifes (size 179) from the demo sale they had. I go to Utah every year for a few weeks and I thought that I would pull the trigger so I wouldn't have to waste my money on renting any more. But the problem is, I only want to bring one pair of skis. Formerly I used to bring my park skis and rent pow skis so I would only have to bring one pair. To cut to the chase, I want to know if I should mount dead center so I could shred park better, or mount em back for pow (by the way I'm 5'11'' 145lbs.) as long as it wouldn't suck in the park.
