Worth absolutely every penny. I have Elixir nickels on my Sire V7, they've been on there for over 2 years now and whilst admittedly there haven't been all that many gigs in that time, they are still almost as bright as when I put them on. I've got Elixir steels on the ska bass and they've lost none of their zing either, despite the bashing they get. I love the way they feel, really smooth and fast.
