I got the same question kinda. but i ride the 13 m800 and i dont see how people say the spindle grabs in the deep powder. maybe i just cant feel it or something. i have a 13 doo and 13 poo as well and i dont see how the spindle grabs. could someone explain a little. i like the big spindles because it gets the upper a arm out of snow more. i dont know. just speculation
For me I have seen in heavier snow the front end really plowing and then in certain steep sidehills I feel it grabbing the hill and washing the sled out. That's my experience in our type of terrain in AK anyways...
