  1. I guess I really don’t understand the point of this video a full year and a half after the rule went into effect.
    Furthermore, you say that the point of this is to show that coverstock and surface plays a bigger role than asym vs sym, yet you didn’t show a comparison between the legal drillings and the “asym” drillings at the same launch angle. You used a totally different laydown point and launch angle.

    I’m just struggling to figure out what this video’s intention is here in 2022.

    1. I believe it was more of the difference between pin up and pin down for sym and asym. They only drilled the weight hole in the ball to give the core asymmetry. Compared to drilling a actual asymmetric ball that would have a different core/cover.

  2. A few questions: 1) if we are really are looking at the effects of layout, why not just use a determinator and measure the time for it to stabilize? Wouldn’t that take all the different releases and ball speed and lane conditions out of the variable column? 2) How much does the starting core shape play intro this? Say a driller friendly Hyroad vs a huge detonator core found in the iron Forge? Thanks!
