I'm a first year skier who is actually picking it up pretty quickly. I'm able to ski fast and parallel on all of the blues at the mountain I go to (Smugglers Notch in Vermont) and I am starting to ski some black diamonds and some woods. I went ahead and got myself a pair of nice ski boots that fit me and they are making a huge difference. Now I am renting skis this year and I originally had an older pair of Volkl AC30 that were 163cm I believe. I went ahead and swapped those for a pair of 169cm twin tip K2s because I thought they were pretty unstable, but in reality it was definitely the oversized rental boot. Now I've been skiing on the twin tip a few times and I notice it doesn't carve/turn as easy as my older flat tailed skis did and it seems to not handle ice well (I'm skidding out a lot because of ice.) I don't know if I should go ahead and go back to the flat tailed or not. I think I preferred the way they skied more, but it could just be the longer ski or some other variable? In your opinion what is better for beginners a twin tip or a flat tailed ski. I'm going to be skiing trails and some woods, but have no interest in doing park. I'm thinking about swapping them for a pair of longer flat tailed skis. Do I really need the twin tip? Is there some advantage to them besides going backwards? Do flat tails preform well in the woods too? And would flat tailed skis preform better in the icy conditions of the east?
Also is 169-170 cm too long for a first year skier that is 5' 10" 160 lbs?
