Unless they have an unusual PAP (and rymacatthedisco is 4" straight over, if you bothered to read his profile), Rico will give a pretty similar roll.
The "dollar value" comes from the cover. After a few years on a high end ball, the cover gets passed down to the mid range line. Pin axis basically takes the core out of the equation. Something like a 2" pin to PAP looks for an early rolling, reduced flare reaction which should help over/under.
I would never recommend a leverage drilling for someone experiencing over/under. Leverage creates the most imbalance, hence more chance for over/under. Your recommendation of more surface is a good one.
I personally would look for a ball with a strong cover with a weaker drilling, and add enough surface so you can keep the ball in the oil longer.
