ThermoQuad info and kit question

I ordered one of the walker kits because of that thread. I couldn't see any particular advantage to that kit just looking at the contents. It looked the same as a Hygrade/Standard kit that I have been using for decades, to me. Judging from the online pics of the kit contents, I was hoping it came with the reusable base gasket, but it came with regular crush type gasket that most kits do nowadays.
