Well judging from your current lineup and without reading your profile my guess is that you like to play the track area and going up the boards is your primary strength.  If this is the case then out of the three you mentioned if you want something to replace the V2 Particle, I'd go with the V2 Strong or the Pursuit.  The Pursuit seems to be the earliest rolling of the new line(besides the Obsession) while the V2 Strong is the most versatile highly aggressive ball in the new line.  The V2 Strong still gets good length but when it gets in the midlane and starts revving it doesn't stop.  The Predator Pursuit is more Roll/Lope/Hard Arc and it looks like a great ball for Strokers.   The Jungle Green might be too angular and the Obsession may hook and die out if there isn't enough oil in the heads and midlane.  The Pursuit would probaly be your best choice with a light 1500 grit sanding to even out the reaction.

Jonathan, you have several options for what you are looking for. For something that hooks more than your V2 you can go two directions: A) Particle - Predator Jungle Green ( this ball will be fairly angular on the back end but still will hook quite a bit overall ) and B) Reactive - V2 Strong ( this ball will be a little jerkier on the back than the PJG ). As far as something that will hook less, i would reccommend the Predator Pursuit. This ball is similar to the origial Apex ( same core shape ). This ball is very smooth throughout the entire lane and very easy to read. Of course surface prep will be a key with each of these balls. You can "tweak" the surfaces to fit into your arsenal a little better. Good luck
