The lone SD-10 scale I've measured has #21, giving a unison 
tension difference between 20-21 of 113lbs. Changing to #22 
wire makes the 20-21 unison tension difference 166lbs. I'd go 
with the #21.

I've thought a scale database - entire scales, not just wire 
sizes, would be a terrific educational resource. To my 
knowledge, none exists.
