I dug the 'effect' they advertised for the strings, but I only got slightly longer life than the cheapies. I recently put a pair of the NYXL's on both my main axes, and really dig them. I need to get better about wiping the strings down when I'm done with a set/night of songs, but they seem to really be retaining their spank after a few weeks. I wanted to try the Paradigm strings instead, but the string website I use had a deal for a free headstock tuner on the NYXL's and I couldnt resist.
I did put the acoustic Paradigms on and really dig those as well...so can't wait to try them on my electrics.
