Ok this is my first post. I am looking to run a compound setup. I have a 62/80 and was goin to get Crazy Carl to hook me up with a kit. I found a BWS400 T6 1.10 new for $600 that I was told would work with my phatshaft, but was told that the S400 that I found was a cheap knockoff. How can you tell, anybody?
