Shane, I ran my stock ski's for my first ride on the Attak. This was at a TY ride in Munising. Couldn't hardly hold the bars it darted so bad. That night in the garage at the motel, I switched out my stock carbides to a new spare set of 8"Triplepoints, 3/8" skisaver. and a 1/4" shim in the rear of the ski rubber. Next day, VOILA!! No darting!! Could run over 100 one handed. No slow speed, medium speed, or any other kind of speed darting. That being said, if you ride your Attak off trail, you'll need wider ski's. The stockers will NOT float at all. I now run Slydog Powderhounds with the same setup as the stock ski's. The Slydogs will need to be shimmed under the FRONT of the ski bumper. I am using 3/8" shims per Scott Bergstroms reccomendation. If you don't ride off trail , the stockers with the above mentioned setup work fine. Hope this helped you make your decision
