You know, the one and only time I tried DR strings I had two break while in the pit orchestra for a musical in college. Never bought another set after that!
I haven't bought roundwounds in quite a while but I used to buy Sadowsky strings. Not a lot of people use them, it seems, but they're great solid strings at a bargain price. They're not fancy or exotic, but intonate well, last a long time, and sound great. I suppose the great sound was partly because I was putting them on a Sadowsky though.
