Query: Pro Arte No Bargain

Bought a set of Pro Arte strings. Installed them on a spare violin, 08/16/12.Last night, 10/13/12 my "A" string broke, and for no apparent reason... not being tuned, or even played at the time.In the course of two months, with only about 5 hours of actual play time on them, they are trash.I figured they wouldn't sound as good as most other strings I've used, but then they only cost $21.Sure enough, they didn't sound as good as a $50 set of strings, but they were apparently already living on borrowed time when I took them out of the envelopes.So much for D'Addario's fancy string envelopes.
