Hi. Looking for some real bright yet balanced strings that last long. Something like really fresh Slinkys and Roto 66. Nickel or coated is just not an option, unless you find one that sounds almost like steel (like Slinkys but long lasting, maybe coated Slinkys will be bright enough, but can't find sound clips). I was gonna go with D'Addario Flex Steels since they sound good, are cheap, realatively easy to find and I've heard that they last long, which does make sense considering their flexibility, but I don't know if it's actually true.
