Utah born and bred. Was one of the first snowboarders on the hill way back when (think Sorels with ski booth liners and Wintersticks with soft bindings and nylon straps you had to tighten every 5 minutes), so yeah, I'm getting old. Spent a snowless decade in Southern California, then came back home. I've never been hardcore; half-dozen days on the hill a year or so (shame on me). I was a mediocre snowboarder at best, but enjoyed it. But I finally reached the age where I became sick of sitting in the snow strapping in or skate-pushing myself around. I decided this was the year to make The Switch. And the year I would get a season pass and start getting a lot more time on the hill.
I'm blessed to live 15 minutes from garage to lift chair and that fine, fine Utah pow. I took five 2-hour lessons in the past month or so. They started me on 150 cm skis. Then I moved up to 160 cm. I felt I had a pretty good handle on those. My parallels were tight and smooth (snowboarding seems to have helped with this) and hockey stops come naturally. I'm not wedging at all. Then I moved up to 170s this past weekend and things went south. A few months ago I got a killer deal on some new Line Prophet Flite skis and Marker Griffon bindings at 173 cm (I believe). I used rentals for my lessons because, well, they were free. I figured for my last lesson I would move up to a 170 cm rental ski to have the benefit of instructor correction before I started using my own skis. I definitely lost a lot with the 170s. My parallels weren't as tight or controlled. I felt like a was flailing a bit. I crossed my tips and went down pretty hard, my first real crash in 5 lessons. I was also starting to lift my uphill ski on right turns. Things didn't feel...right.
So my question is, should I grab a pair of 160+ cm skis to use for a year until I've better solidified my skills/technique? Or should I jump on my 173s and flail around a bit until I have them under control? My fear is developing some bad habits with the longer skis that I will have a hard time getting rid of. Would sticking with a shorter ski for a season be to my benefit or detriment? I know the 170 size is an eventuality for me, but don't know if I should wait a bit and practice on the shorter sticks.
Oh, 5'11", 150 lbs. Groomers for now since I'm a newb.
Any advice from the veterans here would be appreciated. Thanks!
