I just got out and demo-ed a bunch of fatties and I think am similar to you in style of skiing and close in size at 5'5" and 142 lbs. I currently ski an old K2 Axis at 163cm. I tried these out in a 170 and they were one of my favorite skis of the day. And no powder in sight - just a hard packed man-made snow day but these skis were awesome. I found my sweet spot for length on my demo day was 166-170 cm.
