I can personally attest to the quality of Joni's leaders.. I will tell you honestly when I first started using it I beat the **** out of it.. I even got the looped end so tangled that I had to cut off the loop to untangle it.. I then tied a perfection loop to that end and continued fishing.. when I told Joni what I had done later she laughed at me and asked if I had thrown it away.. I said no.. I am still using it.. I thought she was gonna split a side laughing..
