Just this week I drilled a Rising Star with 4 1/2" x 3 1/2" layout with pin above. (But understand that I use pin above due to my low speed & low rev rate so I can push it down the lane.) I find the ball to be so good playing inside (3rd or 4th arrow) on any medium patterns.
If you are high revs and/or high speed THEN you would use your preference of pin below. All it boils down to is how much push you need down the lane when you decide between pin above or pin below.
The ball's core already has a high RG rating but the hybrid coverstock is great on the medium oil (or more oil if you use more surface; I use 4000 Abralon surface).
