I have a 2011 HCR right now with the 153 2.25 powerclaw and i am going to be putting a 162 2.6 powerclaw on it. I ride mainly in west yellowstone and was wondering what durameter to put on the 80 or 85. I have the 90 2.25 on right now and it works good until you hit deep powder. Just wondering what other people have found with the new 2.6 and how the different durameters have performed.
