You can hear a high strung guitar on almost all of Paul Simon's stuff. He almost always plays one (a black Yamaha, I think) on any TV shows I've seen him on.
Ian Tamblyn uses an old Harmony Soverign (sp) as a high strung and often plays it solo. He really makes it work.
I have an old Yamaha that I use and I use the high strings from a 12 string set. Since I don't use it that often, I sometimes replace the 3rd string with a regular G when the skinny one breaks. It helps keep the melody going when fingerpicking.
