Vivid had a unique core that tended to be very rolly, yet angular. The core was taken from the old AZO Area which was a very under appreciated ball. However for most bowlers the strong solid shell on the Vivid is a poor matchup with the core.
The pearl lucid with the same core is much more popular, yet still very strong. I think a relatively tame hybrid might be the best shell yet. I told a couple of guys at storm, before the Lucid came out, that they should put the frantic shell on the vivid core. Still think it would be a good core shell matchup, although my Lucid is a great ball for me
