I think people too often write off headless basses as some sort of 80s gimmick without actually having tried a good one...
having played many gigs with a steinberger XL-2 strapped on me, i can say that headless basses are the
bomb for dinky, crowded stages. the one i owned was a svelte 7 lbs. and change. plus it was a freaking tone monster. it traveled well, i could fit it into an overhead compartment on an airplane. it got x-rayed so many times it probably glowed in the dark. not sure i'd wanna travel worrying about one of my high $, full sized basses in an airplane luggage hold, even in a flight case.
i know a few guit@rists and singers who've gigged with me over the years that probably still have headstock/tuner dents on the backs of their heads from straying into my space on non-steinberger nights. i never poked anyone's eye out with one of my pointy basses, though...
