ThaLowEndTheory,
You're not weird, just tired of the same ol', same ol'.
I like the small round pickups, but I don't like the shape of the first three basses. Actually, it's just the hyper pointy strap button and the (given the designer, understandably) Alembic-like "neeple" that breaks what would otherwise be a graceful line below the bridge.
I do like the next three, although the first of that set is a bit busy looking.
The last one's bulbous body on the bass side seems over-extended, like a sagging butt. It would be a great looking bass if its flab were trimmed.
As for the two-string one-string instruments. What's wrong with that?
I've got a friend who has a two-string ngoni/hajhuj/gunbri and I got to play it. I can play a couple of crazy things on it, but he can make it sing.

An erhu only has two strings; I'd think a Chinese bass player might like the two stringer. In fact, I was at a blues jam this last weekend and the Erhu player laid down some killer solos (bowed, not pizzed).

Gypsy doublebasses often have three strings, as did most basses back in the days of development of the instrument, when 3 was the norm. People convert old 5-string uprights to four and vice versa. String number doesn't matter.
Some bass players readily admit for the type of music they play with the band they're in that they only use the E and A string anyway.
Whamola anyone?
Whatever works for you and sounds good is all that matters. It's a matter of individual taste.
BTW, I LIKE uni, GOOD uni. The problem is I've tasted some vile uni, horrible uni that would (and did) put off a neophyte sushi taster. When it's good uni, ahhhh

Fugu? Alright, but I prefer uni.
Cheers,
FF
