(COPIED FROM HAMMER FORUM)
As far as I have seen the Cell Pearl is stronger, has more backend than the BW Pearl. The Venom is closer, but the CP still handles slightly more oil.
Honestly, can't believe you need a ball with more "punch" than a Cell Pearl. Unless the ones you've seen were drilled wrong or used on the wrong condition, there aren't any with more "punch". Maybe look at MoRich's Nsane or Ntense LevRg balls. They can handle more oil and have a ton of backend.
The Track UpRising also handles medium to medium+ oil, like the Cell Pearl, and while it is incredibly strong, it isn't stronger (more backend) than the Cell Pearl. Same for the Lanemasters Black Pearl Reactive.
