Had a chance to shoot the new black mambaX2 and suphan this weekend and I was blown away, they both were amazingly smooth with no hand shock,not sure which one I'll go with,my buddy who shoots bowtech tribute was so impressed he bought the X2 and he's getting ready for 3d nationals next weekend for a small company they are going to turn some heads as more people get to shoot them.If you have a chance to shoot them you won't regret it.
