I was following the cascade XXX thread (the cascade with 149 jets?) and from what Ive read it seems more jets doesnt help that much, but improves the overall smoothness of heat over the core, because there are less hotspots between the jets.
One question I still have is does jet/cup size (with the right ratio) improve heat transfer much in terms of how it affects the boundry layer.

Also I dont know how easy lost wax casting is in silver, but it seems very hard to do in copper because of air bubbles etc.. I have enough silver for a few blocks but I couldnt find out enough about casting silver for me to try it. Have you done it before and what equipment did/will you use to do it?
