Arrow skis from kimpex track as straight as simmons on the snow and track straighter on curved hard packed roads. The turn as easy as stock skis with stock carbides. I have tried about a dozen sets of skis and these are the best so far. They are about the same foot print as the stock skis so if your trying to float over powder, they will be no better. I have simmons as well and they cant compare. The slow speed steering effort needed to make the turn is a killer and that was on my venture that was a lighter front end.
I love that I can put so much weight on the front end now and the effect on steering effort is nearly unnoticable. As with the simmons, 1/8 to 0 toe.
You can run these skis unshimmed and they will turn too easy but still not dart. I run them shimmed 1/4 to give them more steering effort for a better feel. Kinda like if your car has too much power steering, you cant feel the road as well.
I have been testing different variations of a set of triple threats this winter and they do work good, dart the least of any single carbide ski i have used as they run a shielded carbide(built in easysteer). The thing I dont like about them is that when the trail is hard, sometimes they dont feel like they will break free from the trail. With Arrows, I always know the sled is going to turn and I dont have to hit the gas to lighten the front end to make it do it.
Nothing high tech. here, just two keels for straight line tracking and deep rocker keels for easy turning and great bite in a corner.
below is a link to comparison pictures between the arrows and simmons from last year.
