I have a Bruce's
...custom cover for my RV-9a. It is great, fits well, but oddly leaves a weird imprint on the canopy glass, perhaps where I've leaned on it, which will buff out, though.
It is 4 years old, and is starting to come apart at some seams, admittedly in some places where I've grabbed it to pull taut. It could use a few more reinforced pull tabs.
Bruce's offered to repair for free, but I haven't taken them up on it........yet.
Now I am wanting a lightweight fly cover for travelling, the heavy lined one is too bulky when rolled up and put in the baggage area.
just my $.02 worth
