So I was perusing the site where I order my strings, and pondering ordering DR dragonskins. The 5 string set had a 3 star review because the poster felt he didn't get enough life out of them. He used them for three months . I would find that a great life for a coated string, I usually use my non coated strings for 4-6 weeks. It adds up changing a 6 string every 2-4 weeks, so I use mine past when I would prefer to change them. So how long do you people expect out of a set, we'll say 10-20 hours a week of playtime. Just to clarify we are talking roundwounds, I don't need to hear about how your flat wounds are older than me and still got tons of life, get better with age, blah blah blah.
