I havent used a leash in ten years... unless youre using step-ins you dont need one... how many times have you seen a board fall off a rider who uses strap bindings... unless the board separates from the bindings via the screws or inserts the board isnt going to fall off you. If I remember right a few years back here on the east coast bungee strap leashes were a hot accessory for all those steezed out riders... not for me, but then again im not too cool...
