I agree on the top two balls being the Strike Zone/ Red Zone combo, though many people can save some money if they are smart enough to realize they are the same balls, different colors, and the Red Zone comes polished versus the Dull Strike Zone.
Below those I would have to go with a weak drilled power groove or a Punisher.
Strike Zone
Red Zone
Punisher
IMO that is what I would do, the Punisher is surprisingly strong for me and anytime there are clean backends the ball seems to be usefull. An alternate could be the Power Groove but they are much stronger than many realize as is the Rampage, both can work but surface/ weak layout may be needed for them to fit there.
