I have the Colibert Rail Rider. It is a stout hitch, but over time, I have had a few issues. The hitch has become more difficult to slide. I thought this was due to gunk build up on the sliding surfaces, so I disassembled, lubed and re-torqued everything. Still a pain to slide. Also, when hitching, I now have to manually lock the lever, which used to automatically shut when the pin made contact. These issues could be due to my lack of maintenance, but the hitch is not yet two years old. If I had a spare $1,200 I'd look at the B&W. Better yet, get an auto-slider.
