Ever tried to use on of those benches? stripped drivers and you have to untangle the security cable every half turn. Get a Burton Zip and thank me next time you have to tighten something.
BAH I say! Maybe I've been lucky, or maybe our tools are less abused and the security cables longer, but I've never had an issue. Although as I mentioned above, if you put your board together right you shouldn't have to retighten anything at the hill.
Plus tool-less bindings are your friend
I already carry a cell phone, lock, lip shit and some cash. I'd rather not carry anything else on the hill!
