I'm wondering if a more powder-oriented ski would help. I was in Utah recently and skied fresh that ranged from 6" to 16" in depth. When it got deeper and steeper, I struggled. Admittedly, I'm an easterner and unused to skiing that kind of depth, but I wonder if wider, softer skis would have helped make up for some skills deficit. I was on Head Rock 'n Rolls 95's (180), which served very nicely in the boot-top depth and cut-up and crud, but once it got deeper, I found myself sinking as I reflexively weighted the downhill ski more on steep stuff. It was hard to move or drive the skis to initiate as they were under snow and seemed "stiff", and consequently everything else fell apart.
I'm fully aware that better technique would help (I have few opportunities to practice these conditions here in the east), but I also found myself question if a different ski would have helped me transition to this situation better -- I'm thinking wider, softer. Did a little bit of reading on the "what kind of pow ski?" thread and began to wonder about skis like the Nordica Vagabond, etc. FWIW, I'm 60, 5'8", 170, pretty strong for my age, and ski 20+/- days a year, mostly east coast. But now my daughter lives in Utah and I'm going to be skiing west more than I have. The situations I'm referencing were in Powder Country at PowMountain, McConkey's Bowl at PCMR, and in Honeycomb Canyon at Solitude.
