I've bought these to replace the Elixir's I had on my Ibanez Frix7 FEAH. I find the 10's from Elixir on a 25,5" scale quite stiff and heavy, very difficult to bend and manipulate, so I was searching for some solution. Good old D'Addario did not dissapoint. The feel is really as of uncoated strings really nice and easy to play, which is how it should be. Guitar strings shouldn't make playing the instrument even more difficult for the player.
I have these for two weeks on my guitar so cannot really say how much would they last, although on the package is written 3-5 times longer. I guess we'll see. I am curios how would these compare with Elixir, being advertised as coated as well. Deffinately will update my review after few weeks, to add my thoughts about the life of these. So far very satisfied.
