SGC0054 user for more than 5 years on an LX. I have had nothing but good service from the grapple, and so far no damage. I have moved countless piles of brush, logs, telephone poles and rocks as big as the LX can safely lift. As with any claw style grapple, you want to pin the brush to the ground, and then close the grapple. You get very full loads, and you almost eliminate the possibility of sticks poking your grill.
Good luck on your search.
