I'm using Traxxas joints on carbon fibre rods. I recently changed to them over the Rostock printed joints. I haven't used magnets, however.

That, said I really like the Traxxas joints. Simple to put together, and they only require a single screw to join them to the end effector and carriage (unlike that damn printed ends with three screws per joint...). You will find that some of them will have some backlash (one of the joints I got had something like 0.1mm of backlash, quite a bit). However, a couple of rubber bands around each pair of rods at each end solves this problem (pulls the joints in, eliminates the play). I'm not sure how long people expect the Traxxas ends to hold up. I can see myself replacing them sometime in the future, as they certainly wear (as evidenced by the white lithium grease gradually turning black). If kept clean and lubricated they might last quite a while though.
