I have to say, I'm definitely a convert to the short scale. Having studied the physics of it, I'd always shied away from short scales, having deduced (possibly wrongly) from my dabblings in physics that a short scale should be less punchy, less bassy, and the tension too sloppy, so that there would be less note definition. In short, I'd always thought that a shorty would be everything I didn't want from a bass. And this had been borne out by every non-Alembic shorty I'd ever tried. In addition, I'm a tall, lanky guy, so I don't really have a comfort issue with long scales.
But when I finally got the chance to play a short scale SC, I was overwhelmed. Maybe it's the fact that it's an Alembic shorty, but this bass sounds the exact opposite of what I expected - it's punchier, got more bass and more note definition than any of the long scales I've ever played or owned. I can only assume it's the way it's made. While the string tension is noticeably less than on my long scales (I use very light gauge strings: 30-90), I actually prefer that - it makes bends easier and I can use a lighter touch and more dynamic techniques. Also, the short scale and narrow string spacing means I can whizz around the fretboard in a way I was never able to on a long scale.
Anyway, the moral of this story is: don't let the science of it, or experiences with non-Alembic short-scales, put you off trying one.
