I have made myself a pair of wrecking balls from a cricket ball and 6mm accessory cord for pinch grip pullups and I am currently debating what is the best way to create a knot to hang them. Currently one of them looks as follows:
The objective is to be able to tie these anywhere that has a bar element, from gym, to tree, to home suspension beam or a simple hook.
My original idea was to simply tie the remaining cord to the carabiner and attach that to the nylon straps of my rings. However it would be much sweeter to use a knot that can self hook (i.e. attach onto itself) with some adjustability (terrain is never perfect).
My idea would be to throw the carabiner over and hook it back onto the cords which could use a ladder knot. I put this query to the more experienced climbers / rope savvied folk to see if there is a better option than my idea.
If this is of relevance, the remaining cord available is 1.5m at least on both ends.
