patagonialukeBoth are fun, fairly light skis that you can still ski pretty hard for how light they are. Main difference I've noticed is that the Rustler 10 doesn't love making really big, long turns — feels like the sidecut wants to pull you back across the fall line if you try to go straight and fast on them. If you tend to stick to smaller or medium-sized turns, then both could work. They have a pretty similar on snow "personality" — both encourage skiing hard but light on your feet, finding transitions, slashing turns when you need to, and they'll both still carve pretty well on groomers.
The review on Blistergear mentioned the “doesn’t love long turns” issue on the Rustler 9 as well which I haven’t found on mine after fixing the factory tune issues.
I noticed my pair had a few edge high sections (common on Enforcers skis too) from the factory along with it being quite base high in other areas. I noticed a touch of instability especially over rougher terrain/mixed snow when bases were flat. Light stone grind to flatten the base, reset the edges and it’s very stable at higher speeds now. Can do shorter turns with ease but more than happy to long, high speed GS turns even with its 17m radius. Agree with the “comes alive at speed” comments that man reviewers mention about the Rustler 9.
Makes me wonder how many pairs of Rustlers are leaving the factory with bad tunes.
