Those strings are among the most standard strings in rock and metal, the thin gauge in the higher strings enables easy bends and light playing with the bright tone, and the lower strings are more riffing friendly as they're a bit thincker than the standard set that goes to -0.042. Those kind of strings suit well for metal as they aviod any shrill highs on the lower strings. They are also very good for switching to drop D tuning (on the 25.5" scale) or even half step down,
Those strings however, disappoint a bit with their sound compared to Elixir strings for example. The period of shrill tone you get for the first few hours of playing with the new strings is quite long with those strings, though for non-coted strings they do last for quite a while.
While a good and safe choice, they are not the best on the market.
