Hey all,

I'm looking for some suggestions/opinions...

I've dabbled in skiing for approx 12 years now, but only in the past 2-3 years have I really stepped up my game (making it out 15-20days/season in western Canada). Two years ago I bought a used pair of Head iXRC 800 (156cm) with used Nordica boots. I'm 5'9" and 140lbs; I'm kinda wondering if my current skis are too short? I'm really looking at bumping my technical abilities and aggressiveness.

I ski "everywhere..." powder if it's there, a little bit of backcountry, and a little bit of terrain park, but of course there will be plenty of groomed runs and moguls.

2 shops I was at today highly recommended the Nordica Nitrous, 163 or 170.
Another shop recommended Armada ARU or Line Prophet 90 or Line Blend; which are very different compared to the Nitrous.

Any thoughts on the above skis? What kind of 'changes' would I notice if I switched from my current Head 800s?

Thanks!!!
