Yeah, I'm a huge La Bella tape fan. I like the Blacks on my acoustic and piezo equipped basses and the whites and coppers on my regular basses. I'm at nearly year 15 on one set and absolutely no signs of wear or change in tone. Love em.
I've got the black tapes on my Brice 5 string. I had worried about paying $40+ for a set of strings, but I'm glad to hear they go 15 years. I may switch my two viola basses over to these as well. The D'ddario tapes I have on them now have weird A strings. They don't stay in tune as long as the other three. I would think it's bass related, but it's the exact same on both viola basses, plus it's the same on a jazz I have.
