So.... last night I played my first gig after my one year anniversary with EPs, and I think I was able to pin down my favorite aspect of the strings, the thing I would miss if I switched to something else. It's the front of the note. I played the last set unamplified, so that may be why I noticed it, since it's less apparent when the amp's on.
There's just a little "pop" at the beginning of each note that I've found addictive. I haven't gotten the same effect from any other string so far. I think it may be the one thing that will keep me going back to these strings. I also really like the amount of damping that they have; they have nice sustain, but not that real growly giant fretless bass thing. Each note has a nice little life of its own. I find that to be a really natural sound for me at this point. And the overall balance of the set is just right for me.
I also realized.... I have got to play unamplified more often.
