I love the Elixir Phosphor Bronze strings. Firstly, they sound great. The sparkle off them is just fantastic and, like it says on the pack, they last for ages. They really do.
Now, if I were to have a criticism of these strings it is that they break just a little too easily for my liking. They are expensive. In the .11-.52 pack, the G is a 0.22, It is extremely light. So when I order a pack I always have to order at least one extra G (0.23) because the 0.22 will snap during the first hour of the gig.
The E and B are also prone to snapping quite a bit too but other than that they are great strings and when they don't snap the freshness lasts ages. They are capable of withstanding months of heavy gigging and still sound great.
I love these strings but the whole G thing is very annoying.
