I never used the Constrictor but after reading your response I looked it up on my 3D Knots app and practiced it a number of times. It really does look like it's going to hold very well. Thank you!

As for your 4 foot piece of P-cord. Well you sound just like me HA. I carry one around with me most times just to practice different knots. The neighbors think I'm nutz but hey, at least I'm not alone in that aspect. I also like that you have 1 foot marks on it. That truly does make a down and dirty tape measuring device. Again  thank you!
