I think the issue with the Phantom series were, they were very speed sensitive, as well as very difficult to lay out or understand properly for the time. As you stated, it is somewhat common knowledge now for the most part, as well as track flare on the urethanes still did not create that dynamic a reaction.

The views and opinions expressed by myself are solely those of mine and NO one else, nor are they affiliated with anyone else.

Has anyone looked at the Columbia Vector 1 and 2 (sometime in the 80's)?  I believe they had the standard top puck with a vertically turned puck in the center.  I think this would qualify as asymmetrical.

The Vectors are symmetrical , they just had the puck lowered closer to the center of ball.

See video.

My money is on the Black Axe from JPF i remeber reading a bowling article sometime in the last five years
that stated the Black Axe as being the first Asym

The Ultra Angle had a core that was shaped like a cork in a bottle of wine.  It was a little wider at the bottom than it was at the top.  It was a symmetrical core, not asymmetrical.  The JPF Axe Urethane was definitely the first asymmetrical.  The Eureka Tank was out around the time of the Phantom/Axe as well and it was also an assymetrical.

I stand corrected

Well, accordingly to Mo Pinel all balls are assymmetrical once holes are drilled. So, I would have to say the first ball ever drilled.
