I think the Primal Fear is going to be a better version of the Primal Rage, so probably more of a backend beast than the Scandal Pearl or Inception Pearl. It should fit in the same bag with either of those two.

Scandal Pearl is probably earlier than the Inception Pearl, but the biggest difference between the two is they are symmetric and asymmetric respectively. Generally I don't put a ton of emphasis on that but with the Inception Pearl's core coming in with a .024 intermediate differential that is a significant gap. Depends on how well you match up to asymmetrics in that range.

Personally I would go with the Primal Fear first and if another one was wanted then the Scandal Pearl. Seems like there would be less overlap between the two.

Would any of them make sense for a sport shot and if so which would be best suited?

There is no way of knowing exactly how one ball will match up to a particular pattern as there are just too many variables in play. Now, with that being said, we can make generalizations about "should/should not" or is "likely/unlikely" to work on given patterns. Still, in the end, it comes down to matching ball (coverstock type, core strength, layout, and coverstock prep) to bowler (speed, revs, tilt, accuracy) to lane conditions (pattern, type of machine putting it out, type of conditioner, and lane surface).
