I was not able to view the video. Gave my browser a stroke. What are the names of the knots he used?

Not having seen the video or the knots, I will add that I favor the power-cinch for tents, tarps and just about anything. It is sort of a modified trucker's hitch. Much better than a tautline knot. As for tarp configs, I favor the Holden configuration generally and the Pyramiddle in bad weather.
