First off, I've been with Global/AMF since the first ball, and for my ball roll, most of their stuff has matched up for me. I have heard GREAT things about the CFT (I like them big weightblocks that roll great), and the ball motion of the Darkness looks very smooth, but strong. Global is really rounding out all motions in their lines, and I dig it. Ordered mine, and can't wait to put holes in it (Could have used it this weekend grumble grumble)
