I would look for a gap in your arsenal.
A 6" pin to PAP is further than anything I would recommend.

The hook phase will be very short and angular. Speed control will be critical, no pun intended.
I think that as soon as the ball sees friction it will flip and want to roll forward.

50-6-30........... the totals are for long oil, the Ratio 1.6:1 is Benchmark for you.
You want to use this ball on a burned up longer pattern. There will be friction in the midlane
I would recommend a low flare layout 80-2-35.

If you study the article, the long layout with the 6" pin to PAP was on a symmetrical ball. Farther down in the article it shows the 6" pin to PAP on an asymmetrical ball (description only, no video) and it shows that it will face up sooner. That is if you are using the 50* drilling angle. If you use a weaker M.B. placement (90* drilling angle), then it will flare as a symmetrical

I got my Critical Theory drilled 80 51/2 35, it was against recommendations given here but i wanted to try it. And i works, for me.
It low flare, goes long, very long infact,( freshly resurfaced 1000grit) but still hits solid. Will work medium oil and on the burn in long oil. What i like about it , doesnt flip, just stays in the same roll, as the dry flares are parrell with the wet. So for me it goes straight so no issues hooking in the burn, (too much). But will get back after some comps, as thats when it matters and the real truth shows.

In your original post you proposed the layout 50-6-30.
You drilled the Critical 80-5.5-35. I hate to tell you this but you Did take into consideration the recommendations given. Higher totals, larger Drilling angle, larger VAL angle and shorter pin, there is nothing in the layout that you did not change. I am glad you did not stick with your original idea and ended up with something usable.

The 50-6-30 was the ball drilling in the articale, not what i was going to drill, my mistake in wrting. The ball is working fine thanks, as i said it goes a bit too long, but as it was an experiment i will live with what i have, or may change it.

If it goes a bit too long you can try adding some surface.
