yeah man!
Great question. So I definitely updated the shape to be more accommodating to modern mounts. The -11.5 mount is as far back as anyone might want (ie max directionality & alpine boots inbounds on the FR132). I would say -9.5 would be good for most skiers in somewhat more upright boots, and -7.5 for “modern” skiers.
after testing the first sample a bit now, I have confirmed that I will be skiing the c132 with my lightest most upright boots the most, and will be moving my mount to -10 (I like very far setback mounts typically).
