Recently started using these, the nickel version, and must say they're the best strings I've tried so far. Interestingly on the back of the wrapping they are advertised as strings for the slapping bassist. I do not slap often, they're great for any style. Have them on both a jazz and a bartolini equiped bass. Great balance between each string, the G doesn't zing as with some brands. Not expensive, too. Prefer them to R. Cocco I've been using.
