As an ex pro who was sponsored by butterfly, I totally vouch for this (Under pressure, Tenergy 05 always brought me back home the bacon when it mattered, Dignics 05 failed me A LOT under real intense pressure). I used these two at different stages of my career on my backhand side. Dignics 05 was too stiff for my game, and you may ask (for those that know of me or know me) but Heming, you also used Hurricane on your backhand, what do you mean too hard?
Sticky rubbers (especially DHS level sticky) are different. When its sticky you can have a hard rubber that has benefits of soft and hard rubbers. If not for the stickiness, rubbers are often hard or soft and live with the pros and cons of each.
And to talk about Dignics 09c vs Hurricane vs Tenergy, If Tenergy and Hurricane were on two ends of a spectrum, Dignics 09c stickiness is barely anything to compared to Hurricane. Its a good rubber dont get me wrong, but they market it a as a sticky next level rubber with the reality that its not even close to hurricane, not even one bit. it would be a 3 at best on this spectrum of tenergy - Hurricane
