Skiing Terms

What size should I ride twin tip skis?
I am buying public enterprises K2, but I'm not sure what size to buy. I still think of ski lengths in terms of the old school (anyone need a 203S?). I'm about 5'10 "175 lbs. I to spend much more time on the skin of the east coast, lama, boyfriend of ice and forests of what will be in the park – more would be better for cruising and carving? Any advice would be appreciated
The last skis I bought were crusing K2, 210's. Me gusta mucho., Stable, fast cruising skis. Now, by bumps, the answer is very different. As for the all-mountain ski Public Enemy by his weight, if you're an average skier to get up 164 if you're an advanced skier obtain the 169. If you ski the east coast and not in Park City or in the Rocky Mountains get the shorter skis. THINK SNOW!
