well i don't have the Venom, but have seen alot of them in action In my Evansville league. I compare it to the Widow pearl, only not as much midlane, but really smooth. It is definitly not what they said it to be with a hard sharp backend.
I see the Uprising is way stronger than the Venom, I know there is now way I could ever use that ball in the league I see all these people using the Venom with good results. I would have to throw the ball 25 MPH to keep it on the right side.
I can not give a good comparison because I don't own a Venom, but i can say that the Uprising is a much stronger ball. Someone else will come on here and give you more information
