On one side of the coin, it would definitely be interesting to take a Tommy Jones, Robert Smith, or Dave Wodka back 50 years in a time machine and see what they could do with their physical game and rubber on wood and lacquer.
On the other side of the coin, the 230+ averages you see with plastic are as much a product of the lane conditions as the improved physical games.
