Thanks Nunz - I believe I went for the 8" carbide. I always believed that a longer carbide didn't make much of a difference in packed snow, just on ice. The cross section of the wear bar is what helps on a groomed trail. But I am often wrong with these things..lol
I lookup the Bergstrom solution for sure!
I wasn’t either until I bought one, like all manufactures, they have there issues, but I’m happy with mine.
The G4 chassis for a taller person isn’t ideal though, but a higher seat makes it better.
