So, talking to my good friend and PSO, we ran the coach's eye software and I was having some issues with increased tilt and lower rev rate compared to some previous testing a few years ago. He suggested we try new pitch adjustments that he and others out of his shop had had success with.
Pitch changes:
Ring - std lateral 3/8 reverse -> same lateral 0 forward
Middle - std lateral 1/8 reverse -> same lateral 1/8 forward
Thumb - 0 lateral 1/4 forward -> 3/16 out 3/8 reverse
Results: Immediate increase in rev rate (+50ish), drop in speed (-1mph), drop in tilt (1" off both thumb and finger to abut 1/4" on both), and the quickest/cleanest thumb ejection I've experienced (go figure!) Not sure this type of pitch change is for everyone but it's crazy to see how much of an effect these changes can have on your release.
New balls:
Used Track Proof - 45 x 4" x 20, 4000 sanded
DV8 medusa - 35 x 4.5" x 20, 3000 sanded
Ebonite Polaris - 30 x 5" x 70, Box
Old balls, new pitches:
Brunswick Hero - TBD
Rotogrip Hustle Ink - TBD

Arsenal design is unique with all asyms at the top but it's typical for my builds and how I find the most success.
Cheers!
