They came from La Ronge, Saskatchewan when I bought them. He loved them and has some you tube videos of his adventures. His 150 was C-FUHN. I talked to him a few weeks back and told him I would sell them. He had wanted the right of first refusal, but has since moved on to Piper Pacers. He thought I was $200 too low on the price. If the drifts get hard I don't use them. That happened here a few years ago, so that year I never put them on. Much of the time the snow is suitable here, your snow may vary.
Whoever is serious, just talk to me. I won't be using them.
