I'll try and get a picture later on, but I would like to describe our rather funny hook.
We have bosch extrusion with aluminum gussets (stronger than anything we got on our chassis

) and a piece of surgical tubing ziptied to the interior to increase friction. It's rather ugly-looking, but it sure is easily replacable.
Also, I like #852's hook... very, very cool... was that a spare you were carting along when you went up during award ceremonies, or were you winning Motorola Quality for something that accidentally snapped off your bot?

(just kidding)
