I like the Pro Bond idea. A glue that can be easily scrapped off and doesn't penetrate into the hinge seems like a good idea. The idea about cutting the covering off and replacing it again reinforces my point that the HP's are not user friendly. I got to admit the file idea is a good one. My problem is that I had to mount a HP in the hard stock joining the two elevators halves. It was a job to say the least. In my own particular case my goal is to do things the best I can and still be quick and easy. I have never had CA hinged surface fail and my one trip with HP's seems bullet proof also. If I had to grade the two I would give "coolness" and cutting the slots advantage (soft wood only) to HP's; but the mounting advantage definitely goes to the CA hinges by far.
