Most people on this board will prefer single shocks since it offers less resistance and a smoother ride. For rock crawling and good old trail runs it's really not necessary to run duals. You only really need dual shocks if you're moving quick, since they have to absorb a lot more energy and the shocks turn it into heat. They'll overheat if you run them too hard, that's why some guys run duals, to distribute the load. Anyway, not sure what kind of wheelin' you do but I'd say go with a nice set of single shocks for most appications and stay away from duals...unless you're going Baja racing!
