Replying to East coast pow ski dimensions

Hey everyone, my good friend luckily makes custom skis and has started up a little company. I am purchasing skis from him this summer. I am 5,9 135-140 lbs. and a good skier. I currently have 171 Ar6's and like them a lot. I especially like to do jumps cliffs and the ocassional jibs. I was wondering what would be good dimensions and flex for a ski used for 6inches or more of snow, because I always go to sunday river and do not ski out west more than one or two times a year at most. Basically I don't want to get too fat. What do you think would be a good stiffness, length, width, shape, mounting point etc. I want the skis to be able to shred anything except for ice.
