Since this forum seems to have fallen into disuse, I will reply to my own post

The great string experiment is over. I replaced my strings yesterday with DR Fat Beams (AFAIK it is the same as the Marcus Miller set, except the man himself moved to Dunlop). The Boomers couldn't give the sizzle and growl that the Fat Beams can. They still can be kind of clangy with a pick, but rolling off the treble on my bass's pre-amp largely fixes that. In a mix, it probably wouldn't even be noticed.

I still use Boomers on both of my guitars. Just replaced those strings too. This just in: it is much easier to change strings on a bass than it is on a guitar with a floating Floyd.
