FWIW, when the wife made me change out perfectly good medium gauge Elixir's on her GS Mini in favor of light gauge strings, I grabbed a set of GHS White Bronze from the string box. These are nickle strings (intended to work better with a magnetic pickup) but I have used them for years to get a mellower tone and long life. Before coated strings were on the market, I used them because they lasted a looooong time for me. They sound like three day old strings when first tuned up, but stay that way for a couple of months without significant change. Way better than 80/20 or PB strings, and comparable lifespan to Elixir's without the extra cost.
She likes the lower playing tension of light gauge and we both like the tone it gives the GS Mini mahogany.
