Had Huck Norris and currently running Cush Core. Huck norris are much easier to deal with the install and if you get flat, its easier to deal with on the trail. Running cush core on my main bike now. Install is a pain in arse and if have any issues on the the trail, like a side wall tear, your kinda screwed. That being said I’ve been running my bike hard through heavily rocky trails without an issue with cush core. Only running CC on the rear.
