Could someone explain to me how the bandwidth is in any way relevant? Am I missing something? Surely either way you're adding 5 extra notes so you're getting the same increase in range, so how is extra bandwidth relevant? I genuinely can't work out what I'm missing so I'm hoping some of the more knowledgeable players can explain or dismiss the figures above for me.
The low B becomes redundant at E. With a high C you have the length of the string up to however many frets you have beyond what the G string would cover, plus the convenience of not having to race up the neck for a high note. I think the high C can be much more useful unless the music calls for a lot of low end thumping.

I have few ideas, but none of them includes the number 9.
