Posted on Butterfly Table Tennis Question and AnswerQuestion:Hi Stefan Hope you are well. I was thinking of changing backhand rubber to Tenergy 19. 2.1mm. Would that be OK on my blade. Thank you in advance. Kind Regards. P.S. Have always enjoyed watching your coaching videoes MoAnswer:

This Ask the Experts question was answered by Stefan Feth. He is one of the coaches at the World Champions Table Tennis Academy in Santa Clara, CA. Coach Feth’s response is as follows:Hi Mo, Thanks for your question and interest in Butterfly equipment. The new Tenergy 19 rubber has a softer feel compared to the Dignics 05 and should fit well with the harder feel of the Jun Mizutani Super ZLC. I suggest to give it a try and hope you will enjoy this new rubber. Best, Stefan FethUS National Team & Olympic CoachCoach @ WCTTAwww.tt-champions.comStay “In The Loop” with Butterfly professional table tennis equipment, table tennis news, table tennis technology, tournament results, and We Are Butterfly players, coaches, clubs and more.
