RUNNING BOARDS
1) Polaris. The boards are narrow enough to keep the sides from hanging up in the snow, yet still provide a solid foot location… and they keep the snow cleaned out. However, the foot stirrup design has been known to trap a boot.
2) Ski-Doo. Although you have a great platform for standing and the boards are designed to keep the snow from building up, the width will sometimes bind up in deep snow and cause the sled to high center.
3) Arctic Cat. The running boards work okay, but tend to collect snow on top.
