My two-cent response to my own thread:
What strings have you used, and which do you like on this particular model, and what are your thoughts?:
I've used TI flats, DR Hi-beams, Ernie Ball Super Slinkies, Dr Black Beauties on my 55-02.
TI Flats: My absolute favorite on this bass. Not that great for slapping, but then again,
I'm not great at slapping. I love the warm and articulate midrange, and the scope of low-frequencies available with these strings. The clear, warm, not at all clanky high end is just too sweet.
DR Hi-Beams: I liked the Hi-beams, although I wasn't impressed with the low B, seemed a bit flabby and unarticulate in regards to tone, not feel (the 35" scale works wonders!

). Deep down, I'm a flats player, but these sounded exactly like rounds should, IMO. If I needed a more aggressive sound, These would most likely be first on the list. Pretty nice lows, punchy mids (with some help from the EQ), and clear, bright highs. GREAT for slapping and aggressive fingerstyle.
Ernie Ball Super Slinkies: Too bright 'n clanky for my tastes on this bass, I wasn't impressed.
DR Black Beauties: These are some versatile strings! Playing fingerstyle with some help from the EQ, I could get a lovely warm, deep, punchy tone. Fiddling with the EQ and pickup selection a little more, and I could get a fantastic picking tone. The slap tone was also extremely good with these strings, albeit not as bright as the hi-beams, still bright enough for the "typical" slap tone. I noticed I didn't need as much bass and mid boost with these strings as I needed with the Hi-beams.
What music do you play?
I play all sorts of music at home, and my only "gig" is at my Church accompanying a grand piano, acoustic guitar, and a choir, playing traditional Catholic hymns. (Love that Bach!

)
What kind of tone do you utilize the most?
At my Church gig, I strive for a clear-yet-bassy, cutting-yet-smooth, ultimately warm-n-juicy tone. You'd be surprised how difficult it can be to be heard in the mix with a piano, guitar, and 900-person congregation without being overbearing or being drowned out. I find that TI flats give me a nice and warmly audible "round" tone, and also minimize fingernoise and clanky treble. I can play the transcribed Cello parts high up on the fretboard with ease, and without sounding like a wimpy guitar.
Do you string through body, or through bridge?
I haven't found much of a difference between the two options, so I mostly string through the bridge just for the convenience. Getting bent wire through those little holes is very aggravating.
