Broken at least 4 in the last few years using 10 to 13 lb weights. I use Scotty weight snubbers to help with the erratic bounce. Before the Scotty’s I’d cringe when the weight came up bouncing. In full disclosure my Cannons are mounted on gimbal mounts which I slide into my rod holders so don’t know if that has an impact but there’s no bounce of the rigger and mount.
