i'm probably never going to try a non-balanced set of strings again. every bassist should try a balance set of strings. i had to file down the nut for the E string to fit, so you may have to too. I'd like the E and A string to have a little more tension, even though they are a major improvement from my last set. the E string is so metal.
update: im playing swing 66 rotosounds at the moment. i'm missing the thicker e string.
