I assume we are talking about the Stick. I just have too much fun/options with 6 strings in 5ths. The "bass" side in 5ths goes higher than the melody side. It's really something you get used to with the ability to realize lines on either side (or incorporate both) and the graduation of string thickness with timbre (for chord intervals, or it sounding like 3 instruments). I have tried all the different tunings, including 7+5, but I can't give up the 5ths, or the high 6th(12th) string, which I occasionaly tune High 4th (it's an official tuning-but I was messing with it before Greg Howard).
I had 5ths tuning on my Pedulla PentaBuzz. Stick Strings.
On basses if you're not afraid of truss adjustment and you don't mind tight or loose strings you can try almost anything.
