My last few cats had the mountain seat, its is higher with a firmer more narrow seat.
I get the plush argument, but it really comes down to your style of riding and maybe your height too plays a factor, like scottyr said, some seats just feel more like a dirt bike while others do not.
my issue of a long day on the comfort seat is my hips/groin get sore from the angle, and it’s just not the same feeling powering through a corner, tight to the right as you shift your weight to the inside when you are on the same sled with the two seats.
It’s nice to have options for sure…I have three seats right now for my sled - stock comfort, my 1+1 seat and my MXZ seat…lol.
