I have a Thumblers Tumbler. Will be doing more brass today. My BR brass is thrown away after a weekend match. Only wipe them off during a match. My dies use carbide neck bushings, so I don't have a die wearing out problem. I am a gadget freak also. About once a year I round up a lot of brass and do the SS pin clean. I do like the look, but do not think it does anything to an advantage.
