"In 2014 the International Table Tennis Federation will use a new plastic "poly" ball. Players involved in ITTF event will no longer be able to use the current 40mm celluloid ball. National Associations invariably follow the ITTF's lead so there is a very good chance, you too will be playing with a plastic ball in the not to distance future. But changing to a plastic ball is not with out difficulty and the playing characteristics are being affected.
This is the first in a three part video series comparing the playing characteristics of one of the new plastic prototype balls (kindly given to me by William Henzell) with a current 40mm celluloid ball and an old 38mm ball.
Part 1 - Why the change and a comparision of their physical appearance
Part 2 - High speed filming of tests to compare relative rebound speed, bounce and spin
Part 3 - Players from our Premier Division who have different styles of play and use different types of equipment try out the three balls and give their opinions on them
Parts 2 and 3 are still in final editing and will be completed hopefuly in the next 10 days or so."
