The only recommendation would be for the angled end caps. Because of where the screw is in them, they get a small gap on the upward side when tightening them. I attached a picture as well so clarify. If the screw was centered vertically on the end cap they would have a smooth fit but since it’s slightly lower it creates a twisting moment that makes the gap.
Still love the product and you can’t really see it unless you’re up close and looking at it.
