I have a clip too but find it is too hard on the rope / warp and tends to unwind the lay of the rope. The ring also allows the chain to run all the way thru the ring and the anchor is against the ball so its the first thing to be lifted into the boat.
Anyhoo to each his own.
A set of 9 by 9 Lencos is all the trim tab you need, Just get the basic control, you dont really need the lights. Plan Xmas presents early.
