Thanks very much for the update Derek. I'm very glad to hear that the Fusion will be included in this testing.
As the Maze 4 and Fusion are available with Brass tops that's the pair I'm most interested in.
I already have a Fusion, but I'd like to see the differance in max flow rates vs lowest temps of these two blocks. If I've errored in my selection for best overall performance I want to know before I make my next system in about 2 months.
Thanks again!
