In reply to cwood2887: I'd tend towards using a Rocker (made by Troll originally and later by SAR & ISC) or similar device such as the DMM Buddy with a short extension on a weighted single rope.
Depending on how hard a route is, or how much it meanders or goes over/around aretes/bulges/overhangs etc. and whether I am training to failure or not, I would probably clip in short to a second rope as a back-up.
Provided there is a reasonable length of rope between the top of the route and the belay you can happily use either dynamic or semi-static rope for either or both ropes.
However as with most things there are dozens of fairly safe ways of doing this and at some point you will need to make your own decision.
