I have no opinion on this -- yet -- and it wouldn't do me any good to fight for one side or another out of belief and be wrong.
My browser also wouldn't let me watch the video.
Having said all that, here's what I'd like to see for future tests:
1) Whatever balls were used in this test (again, I couldn't see the video) used on COMPLETELY STRIPPED lanes, for no other reason that to find the exact spot each loses tilt.
2) Same balls, used on a low-volume, short, flat-oiled lane, with re-oil between every five or six shots or so (time-consuming, I know, but if you want to be a scientist...)
3) Then, a comparison test between balls of different companies, syms vs. assyms, and polished pearls vs. sanded reactives.
4) Comparison of balls with different pin-to-CG and pin-to-MB distances from 0" up to 13" to determine whether distance has any bearing.
5) And finally, the biggie: Thrown by a machine and not a person.
All balls would have to be spun with a determinator to confirm markings beforehand. I'd also like to see computer simulations run on each.
Basically, what I'm asking for would cost thousands and wouldn't be practical for anyone to actually do. But if you're looking to make definitive statements, you need definitive evidence, which I don't think you'll be able to get from watching human beings throw limited numbers of equipment on limited selections of conditions.
