Interesting read. I just picked up my 165 VSR xtight asym this morning and took it out today for it's first day. I was a bit concerned after reading your report and to add to my concerns, conditions were firm due to the thaw and rain late last week followed by sub zero weather. I didn't know what to expect but had to try out the new toy(my first Coiler).
What a pleasant surprise. I found it very user friendly with no negative traits, that I've discovered yet. I'm centered on the inserts, 19.75 stance width. Differences between the boards are that mine is only 17 wide, built for 180 lbs and xtight vs med. I'm guessing the med. sidecut is requiring more speed to get to the boards sweet spot than the xtight. That could explain why it felt better on the big hills in Aspen vs. the narrower icier terrain that you're seeing at your home mt. I'm quite sure that I'd prefer the med. sidecut if I had access to bigger hills but for our little Ontario hills the xtight is just right.
Between your Stubbette and your VSR it sounds like you have a perfect board for either big or not so big hills.
Still sorry that I didn't make it to SKES either year. Maybe next year.
