I always wonder if JO Waldner is indeed using Waldner Senso Carbon (WSC). The reason is that Donic Dicon, (or Donic Waldher Offensive Limited 2016) is faster than WSC. This is based on several copies of both blades that I own.
So I am confused as to why he downgraded into slower blade (although WSC is a carbon blade). Most players, due to the glue ban and increase in ball size, upgrade to faster and stiffer blades.
If I remember correctly, the Pong Professor in TT11 blog also stated that Waldner Offensive Limited is Off- and WSC is All+ blade.
By the way, did you all see that the black rubber in the picture has Butterfly logo?
