I have a bunch of tomic plugs in the 5, 6 & 7" size. (just like a women can't have too many shoes. At least that's what my wife says) Anyway I bought another 30 - 40 off ebay this year. About half of them came with a ring through the tow bar. I have always tied the plugs directly to the line using a knot on the top of the tow bar. Has anyone used the rings that go through the tow bar, or should I just cut them off????
