I tried the Black Mamba and OMG during a demo day and for me, the Black Mamba was too much too early. For me it hit weak also due to rolling out. The OMB was a better ball match for my rev rate and the THS pattern that was laid out.
I can see the Black Mamba being good for flatter conditions where you need to play straighter angles up front, but I wouldn't use it for anything else.
