Query: Eternal strings

I love the way these strings sound and they last forever. No. They really do.My acoustic has had the same strings for 2 years. 2 years!! That's absurd. They still sound good, too. In fact, they sound better than they did new because they have lost that tinny "new-string" sound. Now they sound like normal phosphor bronze strings that have been on a guitar for 3 weeks.I was traveling in Europe with one of my guitars that had a 2-month old set of strings. Somebody plucked a few notes and looked up to exclaim, "new strings"! I kind of laughed to myself. These strings have completely changed what I consider to be a "new" set.Granted, they are not cheap, so if you break strings a lot it can get expensive. Clearly, I do not break strings a lot, so for me they are awesome.
