Re: Too much muscle
It's true, one knot is not perfect for everything. I was using the last knot shown on one whip with a long bailing twine (polyester) cracker attached to a stiffer fall.
It was great for the other whips I tried it on, but for that combination, it came off a couple of times. On that one I switched to the second knot that Robby shows (The photos on the orange carpet) and it is holding perfectly.
I didn't really pay attention to whether the flow was smoother with the other knot though.
