I've heard that they spin. My question is what reason do they have to spin and what is to say that each ring spins at the same rate. I know there have been several manufactures specify how they want the rings positioned at install so if they spin freely isn't it a lost cause? It sure is disappointing to think that all your ring gaps may line up at some point is it not?


Why would it matter if your top ring lined up exactly as your second, let alone one of your third ring gaps............. What would happen that is so bad???
