Reviving this one just to see if anyone can chip in with a comparison to Kalium? Bass Direct are selling them now in the UK, but only do 5 string sets, and not in the gauges I want, gonna see if Mark can ship us over the ones I do with his next order if it's any time soon, however I'd be interested to know if they are any good, as Kaliums have sounded ace on both my basses, and they last aaaages if you look after them in a decent bright but worn in state.
