Hi Olson. It looks like you got pretty good stats there.
so it looks like you got a strong pin iin your Primal Rage, and a weak pin in your Primal Scream. Now to confirm, you're getting the original Thrash, correct? You wrote "Frenzy, Frenzy Thrash". There is no "Frenzy" just to clarify
Here's what I'd recommend for each ball, and I'll explain my reasoning afterwards:
Thrash: 70 x 4" x 70.
Thrash Frenzy: 70 x 5" x 40
Primal Scream: 70 x 5.5" x 30
Sigma Hybrid: 70 x 4" x 45
I left the drill angle for all of them at 70 because they're all syms and should be enough for weight holes if they're needed. Because 3 out of 4 of them are solids, I suggest some variety in layouts. The Thrash will be very smooth and controllable. The Thrash Frenzy will be a nice compliment to your Primal Rage if the Rage is a bit too strong and you need to shell down a bit. The 2nd primal scream is to contrast your first primal scream. It's going to get down lane further, and have some backend, but still be fairly strong due to the cover. The weaker pin should allow you to use this on a house shot more often as well. The Sigma Hybrid is pretty strong, and will be good when you encounter some oil. It'll start up a bit earlier but still have energy for the back end.
Hopefully this helps at all. I picked the pin lengths mostly because you said you're bowling on Kegel sport shots. Since you're pretty high rev at around 450, I didn't suggest any pins stronger than 4" because I personally wouldn't think you need them. But I kept two of your pins in the Thrash and Sigma moderately strong for the sake of the harder patterns it sounds like you're bowling on. My rev rate is lower than yours (350-400) and I almost never need pins that strong.
I'm sure someone else with more knowlege than I will also comment on this.
