Dontcha hate it when you get the wave lined up, pop up, and find that you have lassoed your feet together with your leash? It's because you've trained it to stay in tight loops.
When not using your leash, take it off, and hang it by the small (board) side, letting the ancle cuff hang freely. This way the leash stays extended and no loops or crinkles (sp?) are put into the leash.
Hmm, that explains a lot because every time i sit on my board, I always have to adjust my leash so that the actual leash, strapped to my ankle, is pointed outward. This usually prevents being tied up but yeah, I should have better leash habits..
What you want to do is find a nice round cup or glass, also get a good knife with the back of the blade really dull, then go to your car and start it up. once you turn it on, you drive down the street. You'll get to a store that sells surfboard items and you'll walk inside. Tell the clerk behind the register you need a new leash, pay for it and leave. Once you leave, go home and throw your old leash away. Presto, your leash is fixed.
