I just use a simple loop. I like being able to slide the shackle (or let the shackle slide) more to one side or the other depending on conditions. And with the center point of the tow way back aft of the boat, directional control sucks (single engine). Best tow point is centered well fwd of prop and rudder (which I do not have). Way aft and especially pinned in a loop, whatever tow does it will resist your effort to steer. Some tows I just use one transom cleat or the other, at least I know I can steer one way. I hip tow until open water anyway.
