Ok threw my Train and Black Mamba first time last night. Train too strong for the house shot, mine is drilled pin under ring finger OBB finish. Black Mamba pin under bridge OBB finish was good for about five frames on the fresh shot.
The train is the strongest out of the Raw Profit and Bank Roll. For me the Bank Roll is very rolly (if that is even a word). The Self Righting Core make the ball very smooth. The Raw Profit gives me the most push down the lane before making a move. My Raw Profif and Bank Roll are drilled pin over the fingers and kicked to the right of the ring finger. The Train is smooth through the mid lane and makes a smooth move when it rolls up.
If you want to add a stronger ball to your arsenal then get the Train. Hope this helps.
In the bag: Lunatic, Break Pearl, Break Point Pearl, Bounty, Bounty Hunter Pearl, Raw Profit, Nuts Pearl, Break S75, Earth Ball, Train, Black Mamba
