I resently purchased a Garisson G20 accoustic guitar which came with Elixir nanoweb strings.   The sting tone is great but I keep busting .024 G strings about every 3-4 days.  This is getting expensive, can anyone recoomend other strings similar in quality with  longer play time?  I should note that the other strings last 3-5 weeks.  Is Elixir gaving QA/QC problems?
