Dirt/disarm was my general strategy against other rangers. In an extended hunting/fighting time with Ronahan, I believe I took five weapons from him. He was complaining about not having anything to fight me with... which was funny, since I started the fight only having a ranger's staff. It got to the point I would dirt him, and he would flee. By the way, I found enlarged bearcharge to be pretty effective... though like a trip, they could flee sometimes. If I killed someone, it was usually a fast fight.
