You have uncommon clarity, sir. Touche!!I moved on from 4 strings about 20 years ago and will never go back. Besides having more low end, having the low B saves moving all over the neck as much. Plus the lower octaves of B, C and D gives more girth than playing an octave higher. Besides, a 5 or 6 string is just a 4 string with one or two extra strings.
Cheers
