Need an educated opinion from users: who's got the warmest sounding strings out there? I"m still looking for definition and proper tone, but I play with a pick and most of my stainless choices are too bright/clanky. Gone down the nickel only road but haven't found something that I really love. I've been unimpressed with DR coated, Exlixir nano/poly web coats and GHS/Slinkys aren't worth the packaging they come in IMHO. Been moving back and forth with various D'addario sets: Chromes seem too dull/lack sustain, Regular XLs are just "ok" as are their coated ones. Half-rounds are decent but still lacking in the sustain dept to my ear. Thoughts?
