I use the corland thingys lol, but as jack said, they do tend to get hung up in the guides especially when you get a fish close to net and it decides it wants to be free and trys to take off, though I havent loss any fish because of it (yet) I am considering getting away from using them and just use a castwell knot or something and see how it works. Also if one should come off when your fishing and you dont know how to put a leader on any other way well your lets just say you cant print those words on here.

Good Luck
