I've been using Elixirs for quite a while now and have never broken one. There are several positives to them including the fact that they last considrably longer than other strings. (Obviously if they keep breaking on you, this isn't the case).

Similarly to what you mention above, I first became aware of Elixir strings when I noticed a particular guitar player was getting a really good tone off their instrument. When I asked him about it he put it down to the strings. I suspect it also had an awful lot to do with the guitar and the player, but the strings certainly help.

If you don't want to use Elixirs again that's your choice, but I, for one, am a satisfied customer.
