I've used the regular Not Even Slinkys before finding these and had many sets of them. They all went black after about a month, while not being played as often as I sometimes do! These may look to be double the price, but I honestly think they last more than twice as long!
They do not sound QUITE as bright when new out of the packet, but the sound they do have lasts a longer time. Therefore for gigging in a heavy band they are fine, but if you are recording and want the extra brightness, use regular N. E. Slinkys.
