USSSA Mamba is HOOOOT. Way hotter out of the wrapper then previous Blackouts. With that being said I still swing my Blackouts over it. It has an awkward weighting. Not as balanced as the TM Blackout and not as endloaded as the OG blackout. Kinda swings slow during begining of swing and then whips though at the end with my swing, making it hard to control. I find myself hitting the taper on the mamba, not to mention getting under the ball where the Blackouts I'm hitting ss with more control cutting the ball. Also the Mamba is much stiffer on miss hits towards the handle over Blackout. Its weird cause miss hits on it towards the handle feel worse but actually come off with better exit speed then blackout.
