what up guys. i hope I'm not beating a dead horse too bad here but whats the big deal with Ernie Ball's cobalt flat-wounds? i get that cobalt is super bright so using it gives the strings a more round-wound like sound and they give the benefit of flat-wound comfort. what i don't get is they're twice the price of a regular set of Slinky's but sound pretty much the same (thank to the cobalt). do they offer something less conspicuous over standard roundwounds? am i missing something big here or what?
