that pretty much sums it up.
I have a 2.5 High roller, single ply hard compound for the same reasons as you. The 2.5 was only slightly heavier than the 2.35. I have found it was ok as a front, although not as good as a badly worn weirwolf 2.5. On the rear however the rolling resistace is very high. Traction seems good, but I now struggle on climbs to keep up with people that I used to leave behind. Down is a different story
