Rode a 2021 Hardcore 154 last week with the new 2.6 track. It is supposed to be a heavier and stiffer track that will hopefully not have the premature breakdown issues many are having with the 3". The intention of the fingers on the ends from my understanding was to eliminate the wash out effect that people are having with the 3" when attacking a side hill. I was able to side hill it with ease in deep powder as well as in marginal snow conditions and purposely crossed old tracks with zero wash out. So the design in the track works great allowing the fingers to bite and stop that major issue people are having with the wash out effect. That being said, it is only a 2.6 lug. Don't expect it to hook up and climb like the 3' in deep fresh snow, because it does not. Really hope they re design the 3" track.
