Polaris makes a twin-carbide keel that attaches to the bottom of your ski. There are two wear bars made out of square steel, with carbides in each bar. They are then attached to a piece of host steel that you bolt to the bottom of your skis. These should do the trick, although I think they are between $60 - $75 a pair.
They would be a MUCH better alternative to the Polaris EZ-Steer carbides. The problem I have with Polaris EZ-Steers is the fact that your rod is less than half the length of a "normal" wear rod, and the max carbide length you can get is 4". Plus, you have the problem of the front of the steel insert that plugs into the front hole in your ski is the first thing to contact the ground, and I've had trouble with that wearing out before my wear rods do.
I've not tried them, but my advice would be to try the Polaris dual-runner carbides. They look fantastic, and should all but eliminate your darting.
As far as easing steering effort, if your limiter strap is as long as it can be, and the preload on your front shock in your skidframe is set light, you may not be able to do much more. Put on some weight, or put a rock-box on the back of your sled!
