TH400 Pro Tree

I am new to Class racer but I have read a number of threads on the pros and cons of Aluminum vs Cast valve bodies. I would like to know if anyone is running on of Coan's Pro Tree Valve bodies with or without the clean neutral feature. I am considering one of their Big Dog transmissions with a clean neutral pro brake behind a 565 in a 2400# car. It needs to be quick enough for a .400 tree. I current have been using a Grinier brake (aluminum) in a slightly modified TH400 behind a 468

Any thhoughts?
