I currently have about a 6 foot long leash on my longboard...and I absolutely must surf with a leash as I am a dumb kook who loses his board from time to time. My leash is tangling me up with my left foot (I ride regular with left foot forward)...and gets tangled up with seaweed...but more so lately.
Can I shorten my leash? To say 3-4 feet? Or is that a no-no for longboarders? Or is it just a personal preference thing?
