I had never used them before, until last week.

I took my new X-18's out to clean them one night and a couple of them had some bad marks starting.

I got a set of the neoprene covers and it only takes me just a second to slip it back on. I have a brass potato brush hanging from my bag that I clean my clubs with after most every shot anyway. So the cleaning part isn't an issue.

So far they don't seems to be too aggrivating or time consuming.
