I used to ride Nevegals all the time but found they are overly heavy and don't roll very easy. They do however have amazing grip in a wide range of conditions. I currently ride Maxiss Aspen's when it's dry hardpack with rocks and roots and I love them. When it gets wet out I switch to Conti X-King's for more bite and they work really well too. Both tires roll much better than the Nevegals and are much lighter. The Conti's can easily be used as an all around tire if you wanted. We don’t have much sand where I ride but I’m not sure any tire works great in sand.
