How similar, or identical does the plastic table tennis ball play compared to the celluloid ball? Although we test Joola's Super P 40+ plastic ball using Technical Leaflet T3 as a guideline, our observations and conclusions apply equally to all two piece plastic balls.
In this 11 part video series, Preston Table Tennis Association conducted random sample testing of Joola's Super-P 40+ plastic ball and for comparison purposes, Joola's Super 40 celluid ball using the same guidelines the ITTF use, Technical Leaflet T3 - The Ball.
