I concur. 33's will not stay clear of the fender well with a 2" lift. You will find yourself rubbing at some point, regardless of the trail difficulty level.
I also agree that a 2" lift is not appropriate for most any offloading. You are gonna drag. If you're going to install one might as well get a 4" and be done with it. You'll look sweet and be able to clear obstacles on the trails
