Green Mamba vs Train. GM is going to corner harder. Even polished (well, 1 of my Trains), it was smooth. That was drilled 50x5x65. Latest one is oob, drilled 70x4.5x30, and it's still smooth. Freight Train drilled the same way has more back end pop, but is still smooth. My Bank and Bank Roll are much stronger off the spot than the Train series.
