i just called line. they said that some ski industries measure their skis differently, but line's "way of measureing" is the actual ski size, whatever that means. he said that in the past k2 skis have been compared with salomon and the 185 saloman ski would be the same size as a 181 k2 ski. and to *thebusiness* im going to be skiing like 80% park and 20% all mountain. i think that the dude above is right tho, since k2 bought line everything has been the same lengeth measuring method for the 05-06 and 06-07 line and k2 products. if someone could actually still measure their 06-07 chronics for me that would be great. oh and onterio, to prove that some ski brands measure differently, whip out your 04-05 public enemys, and measure them first by putting a ruler ontop of the ski, and bending the ruler where the tip comes down, all the way to the back. it comes out to be whatever size you have(i think you have a 169?) then, just put the ruler on the ground of where your tip begins, not actually on the ski, but like on the ground next to it where the tip starts, and measure to the tail, and it comes out to be a 171. from what i have read, some industires measure before they press the ski(make the tips and tails) and some measure aterwards. its all how you look at it tho.
