Peter @ Team Br00d recently wound some new arms for me and they are working great.
I actually switched over to a Reedy can w/laydown hoods as an experiment and it seems like my slave is lasting a bit longer between re-builds now, and the results are just as consistent as they were with the original can that came with the TD.
