Much as I like the little bit of extra range and couple more note options I have with a five string bass, I'm not sure if I use the B string enough to warrant owning a bass equipped with it. It's fun and all, but i really think I'd be just as happy with a 4 string and one of those D-Tuners from Hipshot. I might try to sell my 5 and get myself into a Corvette 4 string or something. Anybody else ever gone back down to 4 after having been on a 5 for a while? Anybody ever regretted it?
