I like to go for a walk every so often, and I do like to smoke a pipe as I walk. Unfortunately the place I live in is always a little windy, so the tobacco burns fast and my pipe burns hot. I have a few different types of wind caps, they have two metal bits on the inside that hold tightly to the inside of the bowl with the help of a spring. The spring is pretty strong, so I'm a bit afraid to use them lest they damage the rim or the inside of my pipe. Now is this likely? Can these caps be bad for the pipe if used too often?
