Hi, I bought a sharkskin 3 weight and 5 weight. The leaders I used did not have a loop so I had to tie the leaders onto the the sharkskin loop. One sharkskin broke after just 3 days, and the other after a week. I read on another bulletin board that a another user had similar problems with the loops breaking, and was accussed of being at fault for tieing the leader onto the line instead of using a loop to loop. Well pardon me, but not all leaders have loops! So has SA actually gotten so big for their britches that they will sell you a $100 fly line and accuse you of improper use for tieing your leader to the loop? I have used Cortland lines for 2 years and never had such a problem!!
