On the Greenridge Trail we had 8 X's. A guy in a sotck Grand Cherokee ended up behind us on the trail. When we got to a really difficult mud bog that we had to go around over a rock, the 8 X's (some bone stock) got over fine (with some good spring hanger scrapping). The Grand Cherokee got completely high centered and was totally stuck. Does this mean the X is "better" - no, but it does mean you can find an obstacle the X does much better on.
