I use these with my warwick $$, and I play hard fingerstyle and slap- no breakage so far. Tone has mellowed out in the 4 months I've used them, but they're far from dead. Not quite as clear sounding as d'addarios, which I also use, but hey.
+cheap
+great tension for fast and hard play
=doesn't go dead after two jams, but do lose their edge eventually
=sound good, not amazing, but good
-didn't quite fit my 35'' scale fretless I originally bought them for
If you need a good set of rounds for 6string and like lower tension, can't go wrong for the price.
