I play 2to3hrs a day,every day. I found that using the strings the guitar maker recommends is best. I have tried many different brands and sizes,some high dollar ,some less expensive and have found Elixir nanoweb work good for my guitar. I use the mediums[.013-.056],Ihave tried lighter stings that are .001"-.002" thinner but this caused some buzzing on the first and second strings because they sit a little lower in the nut and bridge. It seem that I get about 3 months out of a set of strings.
