I think one of the COOLEST tricks besides the finger pool, and boot shot, is one i seen from a old video.
He puts a ball on the table by the head spot, and takes another ball and tosses it down the table and gets it to curve around the ball and into a pocket. And after every time he moves the ball back towards the end rail, and continues to throw a ball down the table making it curve around the ball and into the pocket.
Massey did it so many times that the last shot he ended up with only a couple of inches of room to make it around and into the pocket without hitting the end rail.
Now Honestly i think the only person who regularly has a chance of beating Massey is Stefano Palinga(sp)
