Portgrinder,
2020 went to new narrow rail spacing, new track, extra tunnel bracing, new brake setup that works great, 2.5" paddles are no longer tapered so more paddle than tapered 2.5 inch "convex" tracks. So as great as they already were, they made all these changes just last year. I'm sure they are always researching new designs, but not really seeing where they can make huge design improvements. Maybe go to a true single rail design like their camso kit but a high quality, light, well suspended version.
Yes, maybe a 3" track for those that want it. Then let real world users decide with their pocketbook and/or real world testing. Snow conditions vary so much region by region and seasonally but for me, there are more days in a season where I'd rather be on a 2.5 than a 3" as the numberplate-deep days are few compared to the 1 or 2 foot deep days and spring days. But others have nothing but deep snow, only ride on epic days, or value deep snow performance on those days more than the problems with running such a kit the rest of the year so I support yeti making a 3" available for those buyers. Or, better yet, we all have two snowbikes in the garage for different snow conditions!
