No contest for me. I still live in hopes that some one will actually make GOOD string. Until that actually happens, I'll continue with the Elxiers. The Polys don't work for me playing slide but the nanos are good. Compared with any other expensive phosphor bronze, elixiers always feel a little dead when they go on but they stay consistent for a long time. On the last 36 date tour, my main guitar had 5 string changes compared with almost every gig with anything else. The guitar that only gets played once or at most twice a night had one string change mid tour and I just recorded with it today. Zero loss of tone or harmonic sequence.
Now perhaps some one could actually apply themselves to some new materials (Maybe) and actually make an uncoated string that will do more than one show. I'd buy it at any price.
