Two Balls needed...one already decided

[Paralipsis]

I currently bowl with a brunswick rattler and a viz-a-ball. I'm gonna get another rattler, just drilled for a fingertip grip, same pin lineup, just drilled for fingertip. I love that ball. Don't wanna get my main one re-drilled as a friend of mine, who has the exact same span as me might buy it off of me, or I'll use it as a backup. Main reason, the full finger grip wreaks havoc on my middle and ring finger knuckles.

My main question for you guys is this, I'm looking for a more aggressive ball, by brunswick (my pro shop has brunswick items in stock regularly, not to mention 3/4s of all items at the center are brunswick, so we get massive price drops on their stuff).

Now, for the smaller ones:

1) Siege, Evil Siege, Revolver, or C-System v4.5?

2) Of those four, which one is more of a backend roll ball?

Info about me:

Style: Tweener
Revs: Mid to Mid-High (depends on the lane condition)
Ball Speed: Mid
Hand: Right

I generally bowl on fresh to less than 24 hours old oil. Lanes are synthetic (at my home bowling center).

Any opinions/recommendations on this?

Revolver or evil siege, or anything pearlized, im not a big brunswick guy. i just got the new storm anarchy early, and man o man that thing just snaps like someone kicked it down at the end of the lane, what a ball

The Revolver is the best ball in their line right now. Very versatile and probably the most aggressive ball they've got. If you added some polish, this ball would be a backend monster.

The revolver looks like a plan. Thanks.,
