Best skis for short slow skidded turns
I'm an advanced east coast skier who likes to go slow (10-20mph), prefer short radius skidded turns and loves bumps and trees. (Mostly-icy-east-coast trees, not powder-stash-trees of the west). I'm looking for a ski that would excel at short radius skidded turns but still able to get a good edge grip to carve across the occasional icy trail.
Ideally narrow (under 85mm?), flexible and lightweight for easy quick turning. All I can find are heavy carving skis or light beginner skis - but the latter come with integrated binding system and I want to use my own bindings (Tyrolia Protector for better ACL safety). Am I chasing a ghost opposite the entire ski industry direction? Or is there a ski like this?
Also, I'm pondering the idea of a shorter ski. I'm 6', 200 lbs. Currently skiing on 170cm, thinking about 160 or even 150 to help make turns snappier and fit better in tight trees/bumps. Besides losing some powder float (not relevant 95% of ski days) and high speed stability (not relevant for me), is there any reason not to do it?
