Stu1961 I’m not going to research the history of hockey pucks. If you want to meet in the middle with tennis as a comparison, I’m game.
You don't need to. They have been the same size and weight forever.
The sticks are not wood anymore. The athletes are not small anymore. The ice they play on is smoother and faster. Average shots are faster. Sound familiar?
No puck "roll back" will happen.
I know jack shit about tennis equipment but, as a guess, I would say there are less aces on a clay court than a hard court, in comparison to how fairways are cut.
