I read the entire thread and you are right, just repeating yourself to me. I was just throwing in my BS about cheap metal. But if my idea of what happens on a molecular level is right, or close, I imagine that is why it has been said by some that after prolonged usage you can't use anything else, I would like to hear first hand what happens after going back, but I am getting the vibe that it works so good that a sane person never goes back after prolonged use.
