Played a couple of matches with the rubber. It is, in my opinion, an improvement over tenergy 05. How much of an improvement is certainly subjective. The spin is definitely more, I found there was better 'put away' power and rotation when you engage with spin/speed. The downside for me personally was blocking, but that may be simply because I did not have enough time to really adjust and tell if it is definitely worse. Serves, opening topspins and put away loops felt great, the grip was first class, and in all, I dont regret the money spent on it. I for one will be using this over Tenergy 05 going forward. One small tip - if you used to boost 05 - go easy on boosting Dignics 05 - as it is just feels softer imo.
