I would like to get good at using brass for lugs. I tried it once and while it probably would have held up fine, I found it rough going. People have told me that brass is just as easy to learn as silver, but I'm not sure I believe that. I've seen some really horrible brazing jobs on bike-boom era European production frames. With silver, a good brazer can have a file-free lug at production speeds.

I have heard of people using brass on stainless, but I'd probably go with nickel silver. It costs about the same and you can use the same flux.
