Replying to Line Blend vs. Line SFB

Hey guys. Alright, so right now I have a park ski, bout an 85 waist whatever you know. Its my only pair right now, but I absolutely love skiing so I'm trying to get another pair to be more versatile. I live in Iowa, so we have mainly hills, icy, fake snow type conditions. Its rough, and I know a slimmer waist on the ski is better for these conditions. But I always go out west for 1 or 2 weeks of solid skiing and skiing in some good, powdery conditions out there. Wondering if I should go with the wider sir francis bacon or the slimmer Line blend. I want something that can still tear up on groomers, but is also great in trees and powder. Lemme know what I should be looking at guys!
