Has anyone used the cushioned ball mount from convert a ball?

We used these on the farm when I was growing up. IMO they act a lot like the surge brake actuator, give the "bang, bang" when stopping / starting. I didn't think it helped much, but we were also pulling huge wagons and trailers, so for something light like our boats, they may make a difference.
