I drilled the new Green Mamba for my wife today and she was able to try it out at a tournament. At first it looked like it wasn't going to do much of anything but after a few shots to get used to it, it started to flip hard through the middle. After a few splits, had to put it away. Definitely needs some oil.
On another note, this thing gets dirty. 1 game and it looks like the pictures. Reminds me of the old white xs.
