As my preference are nickel strings, then I am trying to test them all - previous experience with Pyramids has been good, but this time I was disappointed. It is true that these strings deliver smooth, warm classic tone, which suits best for easy rocknroll and swing (no no for metalheads), BUT - maybe it was just very unlucky case - when changing strings, the upper E (046) simply broke... I put it on tuner, twisted around, started to wind it up, and after few turns it simply cracked... It could happen to small E, but if it happens to big E, then it's not cool.
Overall, as I tinkered a bit with other strings - good sound, easy playing (bending, sliding).
