I'm lucky that I can buy a bunch of skis and unload the ones I don't like. I've logged 43 days so far this year. I would have broken 50 already if I hadn't lost 3 weeks due to being sick. The only lessons I've taken this year have been in the bumps. Last year, I probably got about 25 hours of private lessons.
My boots are definitely not too big. They are custom fitted Strolz and the problems started in February. Not sure why. I've been in boots that are too big before and these are not too big. My heel is locked in and my foot doesn't move at all. The only thing I can think of is that perhaps there is too much space between the tongue and my shin? Maybe I need something to suck up that space. Since the boots are foam injected, they are completely moulded to my feet.
When you saw me skiing earlier this year, you saw me at my worst. It was only like my 2nd day out of the season and I was skiing demos that had a "Colorado tune" while skiing November frozen manmade conditions. IE, a powder tune didn't cut it for that day. It was like skiing on dinner plates. So, if this is your impression of my skiing, you are way off base. I am a much better skier than what you observed. Although... the old saying does apply to me... "it's not that you can't ski the moguls, it's just that you can't ski and the moguls prove it."
Anyway, any idea of a mount point for the 7s? Since I ski my Kastles with zero problem and they are 183, 184 respectively in length, I'm pretty sure this is either a mount point issue OR a technique issue (maybe I need to ski in a more upright neutral stance?).
