Just to get it started, lets see what ya go and what ya use. Pics of course.
Snubbers, a lot of times, say you hook a stump, just the stretch alone will keep the ball from getting wedged tight or it just sling shots it out and it keep from breaking stuff on the boat. The other big one is the bridge anchors on the floating bridges.
Fins, shamelessly stolen from Silver Horde Catalogue:

I go Dr Line, fin, snubber, ball. I like the splatter back for some reason but chrome flashes more.......
