I currently am using an Apocalypse by RotoGrip but would like to add another ball to my collection. I've been debating on getting something for light oil or medium-heavy. I've decided to get a ball for medium-heavy as that is the typical house shot in my area.

Can anyone tell me if the Apocalypse and Triple X similar balls? I don't want to get another ball that basically fits in the same category as the one I already have. I've looked up the RG, Diff/Flare, Torque, Length, Backend and Hook potential for both and both have similar ratings but one says it is for medium oil (Apoc) and other is for heavy (Triple X). Any help would be appreciated.
