I have read the related threads on this topic for the Axys models but have not found a Matrix related thread. I'm new to new sleds, had an RMK years ago, have done lots of snowbiking, and I'm looking at a '22 or '23 Matrix with either the 165 2.75" or 163 3". First off, is there still an issue with the 3" trenching more than the 2.75" on the Matrix platform? Is there any advantage for me a newb to the modern machines with one track over the other? Thanks.
