I've not had any trouble with my bodoodle rest. I use a product called super slick on the forks. It is whisper quiet and I don't have any flight troubles. It is not real durable but they are cheap so I don't mind. There are two types of the super slick rest covers, a white one, which i belive is teflon and very durable and also very loud. There is a green one, which i use, feels like thin rubber. I've had good luck with them. If you are interested i can get you the company address from the package if you can't find them.
