Supraman, I just picked up a pair of addicts in 172. I'm 5'8 155#, level 7-8 or whatever you call a low advanced (I say low because I'm not a bump pro or park rat yet. This will be changing soon). Anyhow, after Mammoth next month I'll be piping in on what I think of the skis. I've heard only good things so I'm pretty stoked. I got them from o2gearshop with a special coupon code, so if you're still looking PM me and I can share the wealth.
FWIW, the tip on the bottom takes up a good 3.5-4.0 inches of running room (9-10cm). Some would argue that for someone my weight (or lack of weight) a running 163cm length could be considered short. If you weigh any more than me I'd consider the 181 if I were you.
Here's a question for any of you guys out there. In the morning I'll be using my volkl S5's for hardpack/fast groomer runs. I'm going to be using the addicts about 50/50 for park/box rails and the rest of the mountain in the afternoon. Should I go with the recommended center mounting point or go a little farther back? The skis are truly symmetrical (114-84-114). My px 12s aren't mounted yet, but just laying the ski down and standing center of boot looks like a ton of tail. What do you guys think?
