Awesome Patriote, I can't wait to see how this turns out. You have pretty much the same components as I do, with the exception of dual pumps per loop. I've got two extra MCP355's with PT tops if you're interested! :P I had two, and I bought 4 from H20 recently. I kept my two original ones as spares since I've heard that once every 25 years or so, an MCP355 somewhere in the world dies.
