Here comes the 24mm RDA that has just been revealed in collaboration with @blueyedgood83. It has an innovative bridge clamp which makes it even more wonderful. The installation is super easy and it has massive builds. Each of the deck and bridge is gold plated and you can make the sleeve to brass, stainless steel and copper.
