We measure our skis tip to tip, true length, not along the surface of the ski.
If you take a tape and put one end on the tail and run it straight to the tip, holding it off the surface of the ski, it will measure 171cm.
I'd expect a bit of weight to be shed next year, but I wouldnt say out skis are amazingly light, they're pretty much middle of the road next to the competition. Bamboo cores are a great material, but we're planning to incorporate a few things next year to make them a bit thinner and lighter.
As for how they will ski, in the 171 J-mo you have about 95cm of ski touching the snow, with a bit more engaging when you're on edge. This compared to 142cm of ski in our similarly sized 171 Blue Steele. Its not going to feel like you're center mounted on a freight train, the rocker will make the ski a little easier to handle, even taking into consideration its slightly wider width.
I'd say its a good pick, but hey, I'm biased. And yes, we always do returns, refunds and warranties, so dont feel like the pressures on or anything. Scott and I are always available via phone or PM on NS, give us a shout if you've got any concerns, ever.
Little of what I do has any meaning or lasting significance.
