I don't use either one, but rather a 'Hawaiian rig'. This has four small blocks tied to each of the stanchions. Through those blocks runs a 3/8" bungee cord with round stainless rings attached to each end -- the bungee runs so that the two rings are between the front stanchions. (It makes a large U shape with the top of the U being at the bow, and a ring at the end of the two tips of the U). Then, the righting line (basically an old mainsheet line), is tied to a rear stanchion, around the same side's front stanchion then over to the ring under the far front stanchion, back through the other front ring, then continue around the far front stanchion until it is tied off on the other back stanchion. The result is an upside-down U, with the bottom of the U having crossed-over line. The bungee keeps the line mostly from drooping in the water.
During a capsize, pulling on the line over the high side's hull then extends the bungee and permits righting the boat. Let go of the righting rope and the bungee returns to its original 'ready' position.
