my mates a courier and he just uses one of those minis taped up to protect the tape work. ideally i'd have one of those on the front wheel with a new york noose through the back wheel and frame. No ones getting through the noose with bolt cutters, an angle grinder maybe. i know d -ocks are susceptible to prising tools and i've heard rumours some can be drilled straight through the lock.
