I go both ways. ;-)
[Boring Music Geek Stuff: I have a cheapo 5-string with a loooong neck that I mostly play as a 4-string because the 5th string won't stay in tune. I've been thinking about getting a real 4-string (i.e. a plectrum banjo), but my cheapo has a plectrum-length neck, and the length makes it uncomfortable to play for long periods. Never tried a tenor banjo.]
