In going up the tower to various conductors, the current tends to pick the
LONGEST conductor path "near" the top for the greatest current. Particularly
on 160 where a 1/4 wave is 125 feet, the typical longest path from a given
junction has the lowest Z and will therefore accept the majority of the
current out of the junction.
How this plays out with respect to "first" hat/wire is a purely case-by-case
basis.
.5 times longer may be as good a "swag" rule as any.
