Greetings from Finland!
I'm just getting back to skiing and I actually bought a pair of Rossignol Experience 80 without demoing. (we don't have a lot, if any demo chances where I live). I Bought them in 168cm and found them too short. I'm 5,9+ and 180lbs. Also I found that on hard pack the partial side wall just wasn't enough. On softer slopes and on groomers I liked the ski quite a bit but I still sold them and am now upgrading to Experience 84 since I liked the ski otherwise. Now my dilemma is.. is the 2cm with the full sidewall of the E84 enough or should I go for the 178cm.
Skis that I was able to demo and that were for sale. K2 Amp 80 XTI and K2 AMP Rictor 82 XTI. Both in 14/15 model and 170cm length. Didn't like either of them too much and found that I even liked the Rossignol Experience 80 more. The Amp 80 just felt all over the place and the Rictor lacked playfulness. Maybe a bit too stiff ski for our local slope and my skills.
As my skill goes I'd say I'm a strong intermediate/low advanced skier.
I will be skiing on piste in variable conditions in our local small slope and do weekend trips to a bigger slope.
