I use D'addario' for my Ibanez (RG's) (009 - 042's)
I use Fender bullets for my
Fender strats (009 - 046's)
I use Elixrs for my acoustic guitars (010 - 046)
I find that the D'addarios last a long time, I change guitars reasonably frequently during play, so I tend to get a lot longer out of a set.
The Fender bullets are 'nt too bad, however they do get mellow quite quickly even with light use. (some people like this apparently).
The Elixr's sound great, I have only just started to use these so I can't comment on durability.
I absolutley HATE D'addario acoustic strings, they lose tone very quickly and feel horrible to my hands.
I usually buy all sets by the box. I have a few guitars so it works out cheaper in lthe long run like this. Cost is about $100 dollars AUD.
