Grenade

1980’s coverstock meets a year 2000 core design. Roto Grip used the Photon core found in the new Riot and Dark Star. Just added an old school urethane coverstock and you found a secret weapon. This won’t be a benchmark ball but I can think of several conditions that you could benefit from the Grenade:

Short oil
Really clean back ends.
Long format tournaments when the oil pattern disappears.
PBA Cheetah and Viper patterns on high friction surfaces.
Anyone with a high rev rate.
Great for practicing.

Great addition to the Shield line and maybe well overdue. I would keep it away from oil, where the reactive resins absorb oil the urethane picks up oil and can become a bit slimy.
