I like the discussion and justification for the 5/8 inch hole to restrict
coolant flow, for all the reasons given.

I have been one of the most vocal opponents of 5/8 coolant hoses - because
they impede flow and probably (I assumed) reduced cooling capability of
system.

5/8" restrictor?  5/8" hose?  Is there a difference?

Would using the lower cost and more flexible 5/8 braided hose give me all
the benefits of the 5/8 restrictor?  Is there something I'm missing?  This
seems to be a contradiction - need big hoses to promote cooling flow and
need to restrict flow to improve cooling.

We have one AC example with 3/4 hose and series radiators that is not cooling.
Then we have Tracy's system with two 5/8 hoses and parallel rads that cools 
most of the time. At this rate it will be five years before we have
enough empirical data to draw conclusions. If you would like to be
part of the applied research group install a system with two 1/2 hoses so
we can see if that works or do you want to fly? :-)
