Definetly bring the prongs in a bit.
Are the prongs rigid or can they bend?
The whole advantage of using the old re-bar ones was that you could put some power to em and bend the prong if it got stuck. The you could either heat it and rebend it or just put it in a press and bend it...
Putting a ring and rigging it to breakway is a good idea too...
Aquaman, those a too purty to throw overboard though....
