Hi Derek,
Usual strategy is you run an idle one size larger. Usually.
It's an experiment based on numerous, inter related variables.
I have webers with 2 drillings (45DCOE 13)
Depending on the exact model, You can end up with 2 - 5. Different locations,
different sizes.
Oh. And for all those with SU's, contrary to popular opinion, you don't need
to adjust webers once they are set.....
;-)
Best.
Chris
PS. Probably Less adjustment on Webers than SU's
SU's are far more maintenance than Lucas Points...
