i've only just started using elixers so no experience on it snapping on me yet, but so far they're good.
i tried the b52s, didn't like em at all. they had a really stiff feeling to em. had dead feeling to em when playing. they didn't sound dead at all, just felt dead.
ernie balls feel great and sound great...but...they only last me 1 to 2 days. 3 at most.
previously before the elixers, the best feeling, sounding and lasting strings for me were dean markleys. been using em for years. now i've just tried the elixers, i'm deciding whether to stick with em or switch back to dm(cos of the price). if the elixers last me really really long, then i'll stick with em. cos i really like em. hah.
