While I think the videos should be of good bowlers throwing the ball who can be consistent so you can get a clearer picture of how the ball truly reacts, I do think they need to be shown on several patterns. If I did reviews on bowling balls on the house shot at my local house, you would never see anything different, everything does the same thing. A Slingshot looks like a Jigsaw Trap but with more backend at the house I bowl at, very short light oil, so the hook monsters burn up and smooth out and the lower end stuff look like beasts.
That's just like, your opinion, man.
