I go through similar periods of indecisive GAS...
Having owned a fan fret Dingwall AB1 5 string (and an ABZ 4 string) they don't hold the same appeal as they once did. I own a better sounding standard scale 5 string now.
I've recently been playing my "son's" Mustang bass a lot. Feels great, weighs next to nothing... it's got me thinking about a quality, dual-pickup short scale like a Spector Bantam or a Sandberg Lionel VT, although they're like hen's teeth!
