Replying to What equipment?

So here's the background. I have a pair of those blue Scratches (168cm) with Marker bindings that have a decent amount of plate under them for control. I do a lot of all mountain stuff and a lot of park stuff too. The edges on the Scratches are starting to get pretty rounded off under the boot from rails, and it pisses me off when I can't turn properly on the ice and stuff on the East Coast when I'm trying to race my buddies down some of the steeper slopes. So basically I want a setup of 2 pairs so I can switch between park skis and a pair that I can keep the edges nice and sharp on.

What I'm thinking right now is find a pair of twins that will handle the rest of the mountain nicely, something longer too, put the Markers on those, and try to find a jib binding to put on the Scratches, but put em more center mount this time instead of the line. I saw some MadTrix for $200 in 180 so those would be what I'm thinkin about at the moment.

Advice?

Have you ever seen a little kid slide back down the inrun of a kicker without going over? This is why parents shouldn't dump their kids off anywhere near the park...
