I have used inner tube scraps or rubber tape on the stays and have added a bushing over the bolt to avoid the over tightening syndrome. I have a couple of Raleigh built kickstands that have a block that goes in between the stays to keep it from crushing and rotating. I also have a few bikes with kickstand plates (amazing invention) as well as a few more that have the mounting tube welded on.

To each their own, I prefer them on most of my bikes.
