Actually, those ropes come from the gliderport that I fly at.

They did the work in a university lab to show that the rope design works
well with knots at both ends and an appropriate device to make the glider
end weaker then the tow plain end as well.

They have the documents to back it up too.

The Pics come from there because a couple of the writers were flying from
that glider port at the time. In fact nearly all of the pics are from this
glider port.

Over the five years that I've flown at this glider port, the ropes have
worked very well and most anyone can re-tie the knot when the rope starts to
look worn.

If you care to contact me offline, we can discuss more

Free is nice but it is too bad the handbook is so full of errors and
mis-information. Who ever had the final editing responsibility failed
totally.

Can you believe an official FAA publication shows tow rings attached to
tow ropes with knots? Where in the world did they get that from?

That is just the start.
