Traction, by track

Studding is decided by the track, not by the sled. Ski-Doo and Polaris sell the same model with two or three different tracks, and they do not take the same stud.

Woody's and Stud Boy measure studs differently and their riding-style categories are not the same categories, so the two columns are shown side by side and never blended. Both are checked against each other on the machine facts they do share — lug height and track length.
