What Tires Should I Buy

I mostly ride desert ie; Ocotillo Wells, Stoddard Valley, Splangler Hills etc. Ocotillo Wells has alot of sand with hard pack underneath, the other places have loose terrain and some rocks. I currently have Maxxis Cross IT. I think I should go with a soft terrain tire. I like Maxxis and their prices are phenom. What do you suggest. I never used a soft terrain tire. How do they hold up, wear etc?
