The more I think about it I think we are going down the wrong path.
Move the tow-hook to the CG of the towplane and the problem pretty much
goes away.

Back to some sort of bridle from the wingtips so any pulling vector is
through the CG (or close).

I'm sure that would work well in the air, but isn't there a potential
problem during the landing roll-out? With no tension on the tow rope it
seems to me that you've got a U-shaped loop of rope dragging on the
ground behind the tow plane which would provide considerable drag on a
grass field if it isn't recently mown. Would this also be a problem at
the start of the take-off roll?
