I recently became interested in mostly copper mechanical mods. I like em, limited tarnish problems, should be low maintenance issues. Although I am not sure what the Golden Rule thinks of them.
There is the Vanilla mod, the Overdose, and the Akuma. I believe some of them have some brass in them besides copper. I am going to try two out of three of them, the clones, that is , 300 bucks is a too pricey for me, even if it comes with a tugboat.
but copper mods???? Yeah i like em.
