Optima 1747.M

High quality strings, balanced warm sound. They also stayed in tune very quickly.
Playing time, yet to be seen. I have noticed the 1st and 2nd strings aren't wrapped like other strings of lesser cost (at the ball end), but doesn't affect sound.
I also think I might be one of the few who has ordered a set of mediums, since the low E string has a slightly darker color than the rest of the set indicating a set that was sitting a while. They're on a Taylor 710.
