Climbing pro made of knots?

Would you whip? We finally tested textile passive pro like they use in the Czech Republic. Ropes really deform a lot!

I think a drop test is better instead of using real rock. Knots do deform, but I think that the force applied in a fall is for a short enough time frame that you won't have the knots pulling out and the rock vs non rock won't make as big of a difference.

no...

The knots look kind of bomber.  I'd feel confident using them.  Until they failed.  Spectacularly.

7mm cord tricam knot (probably not the right name). I have placed and fallen on it. It did not deform significantly but did take a little effort to get out. There was no appreciable damage to the sheath. It would be nice to know if it holds better than some of the more common knots you tested.
