So I've read all about the light wedge. Actually have one ordered for my niche. I also have a replacement sealing ring on order. I think that's what it's called. The stainless steal ring that actually has the tab on it. All things being equal, which would you use?? The wedge is obviously cheaper and probably easier/faster. But replacing the ring seems to be the "right way" to do it. Also, what happens when I remove the six screws to take off the old ring? Don't want the whole niche to come apart.
