I just took delivery of my brand new 185cm Dynastar Huge Trouble skis (140-115-130), and I’m currently in the process of trying to work out where to mount them. The very detailed review that sold me on the skis makes a convincing case to mount them at -3cm to hit the sweet spot in the turning radius. I’m convinced that most twin tip skis are mounted too far forward, which might explain why all but he most aggressive jibbers I see seem to be leaning back and fighting for control. To confuse things, a tech from Evogear told me to mount them at +2cm else they wouldn’t perform on hard snow. I’m going from my 183cm Head Super Mojos, which I love, so to try to sort this out I measured what I estimated was the functional side-cut length (ignoring the tip and tail) on each ski and produced a spreadsheet comparing the relative positions of the manufacturer’s centre mount positions. My Supermojos are mounted (on the line) at 43.54% from the rear. The manufacturers mounting position on the Big Troubles is at 45.91% from the rear. At -3cm the mounting position on the Big Troubles is at 43.97% from the rear, seeming to confirm the review I read, and which I’m hoping will deliver the feel I’m looking for. These are going to be my day to day resort skis, but with Dukes mounted on them so that I can skin up to Motherlode on big days, lap Roberts occasionally, and perhaps use them for cat-skiing. Bring on the powder.
