I've had my beloved Battle split,a horizon solid, and one of my favorites, an RSP split.
Also, had a Vortex, a One, and a Killer Instinct pearl crack on me as well.
From personal experimentation, ya gotta put these balls on the lanes, and get oil in the pores, or they will dry out and crack, no matter who the maker is.

Duct tape is like 'The Force'. It has a light side and a dark side, but it still holds the universe together.
