Studs or bolts will make no difference with leaks. Guys make multiple changes when addressing a leak and just make the assumption that the fastener change helped. If the fasteners are backing off, that is a different issue to be corrected.
Same for the idea of synthetics causing leaks. Guys make the switch and then start checking carefully for leaks and find the leak that was already there. Boom, synthetics cause leaks. Where it get funny is when someone tries to gain credibility with their argument by stating how long they have been living with their own ignorance. Not saying it's happening here (yet), but that's normally where these discussions go.
