I don't think they are necessary if you are fishing the great lakes, and it sure isn't necessary to pay the ridiculous price of the "upgrade kit" I like a lot of others made my own. I used downrigger cable on mine and most guys have the red clips anyway. Now the spring is the one part you may need to buy as I frigged around with a bunch of different springs that never worked right so I ordered a bunch from Off Shore. If you are in Kingston bring them over and I will do them for $10.00 a board including the spring.
