The feel under the fingers is rougher that nickel plated strings, so maybe if you like sliding a lot, be a bit careful. Adding this to the medium gauges in this pack, it means that they can be quite hard to play in standard tuning (34" scale). I have used them mostly in D and D# standard tunings and they were much easier to play.
That said, the sound is nice and bright and are lasting quite a long time (had them on exactly a year since i bought them and am still enjoying them), but as usual your mileage may vary, depending on how much you play and many more variables.
Overall I am very satisfied and will most likely keep buying them.
