      - If bolt's connecting it to the towbar fail, you have a big piece of metal flying at high speed.

      + Can be made save if used with lanyard connected to rope and differnet point on vehicle.

      + big bolt with a large surface area on rope eye.

      + Quick to assemble, and get to if chassis in sand.

    • + Rated, attached with two bolts.

      + Open, does not need shackel, just hook rope, less metal to fly.

      - If bolts break, hook fly's off on kinetic rope, but as rope slows it can fly off on it's own.

      install directly on chassis, one on each side, and use bridal (>3m) to spread load over both.
