hey, im not completely sure on this but, i got these new(used) skis this year, theyre '05 Line 1260's and theyre 164cms, im wondering if this is ok for my height and weight (6ft, 165lbs), or if its way too short, ive used them 17 times this year and they seem to work well, its just that i was wondering (btw ive been sking for 7 years, so i dunno if that makes a diference, oh yeah, and this is in reference to twin tips ONLY, i can pick a good size for myself for regular downhill skis)
