I was planning on center mounting them. Longer than 169? I'm not sure since I skied on 160s last season and at windells and was comfortable. Is this just your personal preference or would a shop guy actually tell me to go longer?
At 5'10" I would go longer than 169 considering the centremount and rocker. But if you prefer a shorter park ski then the 169 would suffice as it will porbably measure longer more like 172 (k2 still measuring short for next year?).
i'm shorter and lighter than you and i thought the 169 was too short. I would go 174 at least, such a soft ski you will not regret the extra length. I had a go on the 179 and it was much better than my 169 (i'm 5'9 135)
K2 measure approximately 3-4cm longer than the stated length. K2 will be longer than any other ski at the stated size.
