If DD was making changes on the 'fly' (and improving flow channel area) then your statement is valid. I can assure you that my mazell is very restrictive and a 3/8 line (id +/- .30") with a 190gph pump still builds a considerable pressure head at the input to that block.
I would suggest that the more restrictive unit be used on the cold side.
