I am trying to find the right length for the k2 pontoon. First i am 5'8 and weigh 190 lbs and a advanced powder hound. The last few years i have skied the k2 apache chief in a 174 and felt like the 174 was not to big at all. I have gotten mixed reactions about the right length pontoon i should get. I am looking at the 179 and the 189 . I just read in this years powder buyers guide and found an article on rockered ski lengths by shane mconkey and found the info very interesting to say the least. It said rockered skis ski short and should be bought long. He said that we should go up 10 cm from our big mountain set up. I did the math and came up with 185 cm . for the proper ski length . As we all know the pontoon comes in a 179 or 189 but not 185. Should i go with the 189 or stick with the shorter 179. If anyone has advice or an opinion on this subject please let me know.
