Some woodcockers shoot #9. Doodles don't seem to be as heavily feathered as bobwhites and 9s would bring them down shot at close range. Dogs used, of course, to find and retrieve a higher incidence of cripples than one might encounter with heavier shot.
I prefer #8 and #7.5 for doodles and wild quail shot over my dogs. RST has or had a woodcock load in #10 for one of the subgauges.
I don't shoot clays which explains my mediocre shooting skills and my relatively intact hearing.
