Congrats Rusty,
And, yes a single ebony stringer, with the neck recipe as you pointed out as credited to Will (Gunn), is both a visually stunning and a tone monster.
Just enough (extra:-)) bottom and sustain without it being too much!
Rusty,
My Custom Series is also patterned, (and inspired/ordered - with Will\s help), after Will\s neck recipe/thickness criteria for the wider ebony, thin Maple pinstripe and Standard (Purpleheart) or Vermillion in your case width of the stringers.
