These leaders are a result of testing many different styles. These are the best I have ever used. Made with 100# test fluorocarbon, 200# test snaps, and 200# test ball bearing swivels. I have re-enforced the loops with tough, flexible, pvc tubing to strengthen the stress points and added salt water sleeves to eliminate slipage. Each end is mushroomed in case the sleeve fails the ends won't pull through. I have never had one fail....
