I owned a long scale Distillate for 8 years, briefly had a medium scale Spoiler, and now own a long scale 5 string Elan. The Distillate was surprisingly well balanced, and I didn't feel like the first fret was way out there. I really wanted a medium scale, so I tried the Spoiler. I liked it, but it didn't sound quite as good as the Distillate, so I sold it to Chicago Music Exchange. About a year ago, I bought a medium scale Warwick 5 string. I tune it EADGC and it's a really fun little bass to play. (I also ditched the bass/treble preamp and installed a low pass filter) I've been searching for an Alembic to take the Warwick's place, but a medium scale Alembic 5 is tough to find. I settled on a really nice long scale (the sunburst Elan), and while there is so much that I like about that bass, it's not really working great for my intended purpose. I may just stick with the Warwick, sell the Elan, and go back to a 4 string Alembic.
I've owned a few short scales (Kramer 8-string, '73 Guild JS-II, Epiphone RumbleKat) too. I've strangely found it easier to go from long to short than long to medium. Not by much. Maybe just because I've played more shorties. And to add to the fun, my favorite long scales (Rickenbacker) are actually a little under at 33-1/4''.
