Bigger is not always better.
With Es from W4 or W5, what beamwidth is needed for typical Es opening ?
Does an Es opening from a southern QTH extend from W1 and west to Minnesota
at the same time?
Do you have DM/DN/EN grids all in at once ?
EN/EO/FM/FN/FO all at once?
Can it be 45 degrees of azimuth wide ? 60 ?
Is this beamwidth needed? Can less be a disadvantage ?
( i.e. 8ele yagi - 13 or 14 dbi with 40degree beamwidth.
11ele yagi - 14 to 15 dbi with 32 degree beamwidth )
Usually from here, at a given moment the opening is much narrower.
