Silicone sax pads seem like a good idea (at least to someone who doesn't know much on the subject). Some presumed advantages: they should be airtight; stable in different climates; maybe longer-lasting(?). I'd like to try to make and test silicone pads. But before I get into it a lot, I'd like to know if this has already been well-tried and rejected? If so, what were the issues? More generally, I would love to hear from anyone who has some experience or knowledge on the subject. Thanks.
