needless to say , off the shelf spools of mono are gonna test out at least the rated strength and above . i started with 15 lbs. of weight , then 17.5 lbs. , and then up to 20 lbs of weight . i was able to lift 20 lbs. of weights completely when it failed . this knot is easy to tie under adverse conditions ( ie bobbing around on plastic kayak ) and is very compact and strong .
