I've used quite a few different strings, from Ken Smith to RotoSound to Boomers to D'Addario Nickle to D'Addario Steel to a number of brands that have faded from memory...
Boomers always seemed to be had for just a buck or two less than everyone else's, But I've never had a complaint for quality...Back then I changed strings every two-three weeks, and the band was paying for them, so longevity wasn't a consideration.
I had a love affair with Swing Bass (RotoSounds) for quite a few years, but they were pricey as shit (post band-paying-for-them days) and I would boil them twice to squeeze extra life out of them. Piano string clarity...
I have D'Addario Steel strings on now, remarkable clarity and life (the set on it now has been there for over half a year), but damn near clinical clarity; The RotoSounds were a tad warmer...The steel strings really expose your technique and style...I might never have tried the D'Addarios except that the concert venue that I do contract work at has a closet full of stuff left behind by bands, and one of those things was a box full of steel wound, nickle wound and .09 XL Red guitar strings...So I'm set for quite some time...
...I would say that for the buck, the Boomers are the way to go. If you get in good with a salesman at the music store they can be had for WAY WAY less than the $35-$40 you see on the sticker. I think I paid $12 for my last set of medium-light Boomers...
