Basil is one of the all time best IMO, either with pedals or no pedals, and he is also a great country E9th player. He is also hilarious and a true fountain of knowledge!
This is one of my favorite of his vids, I've listened to it regularly for years:

Great version of Sand using
E C# A F# D# B A B (no pedals)
And his version of Body and Soul on his unique copedent is so beautiful... I don't know if his pickups are particularly hot, but he does have a second one added on the pedal neck. I know he uses digital delay.
I agree with Jim above on
E C# A F# D# C# A B, that is also my favorite B11th.
It is two strings closer to being the same as fifth on top 6th tuning with more F# minor 6th and A major 6th voicings!
Even with 6 strings I might prefer a C# on the bottom instead of B.
With 8 it is a no brainer, personally, because the low B is there on the bottom when it is needed.
I guess a lot of people prefer
E C# A F# D# B F# B because it was used by Jules Ah See, but I also wonder if it isn't because it same intervals as P7 and P8 together on C6th PS, as you mentioned.
Tony Locke whoops ass with
E C# A F# D# C# A F# and that is even closer to A6th!
