I recently had my RR line rupture on my 2000 MT. I've read through a few threads, but was wondering if there was any more definitive preference on the replacement material. It seems that the copper nickle lines are easier to work with and are likely less expensive. Any further pros of the stainless lines? It seems that some people are having trouble getting in touch with Ski Bristol about the group buy. Unfortunately I don't have a lift available and the car is completely without brakes. As others have noted, it makes sense to do everything in one go since all of the lines are not in great shape, but was considering potentially a temp replacement of the bad line to get it driveable again to maybe wait for the stainless lines. I'm sure I don't want to go the OEM route.
