My buddy is a Yamaha dealer and recommends the Camoplast Tatou 4s system majority of the time. Less cost, easier to get replacement parts if needed-make in Canada.
The Yamaha dealer in Prnice George is a distributor for the Mattracks. Sweet setup, most surface area cover in rough terrain BUT also most expensive.
Call your local dealer and see what they recommend.
I have road in a Rhino with tracks a few winters ago with another consultant-rhino was fully enclosed cab with a heater. Quite impressive inthe deep snow in the cutblocks. He did pack a chainsaw as if needed when issues with hidden logs and trying to back up, the attack angle would not allow rear tracks to get over logs.
Maybe things have changed a bit since then .
