I tried D09c a couple years ago on my forehand side while playing penhold with an offensive hardwood blade. Coming from Hurricane 3, I found it very difficult to control because of the high throw angle. My loops often went long. I could not touch the ball softly, which is a big part of my game with H3. For a penholder, not being able to touch the ball softly negates a big part of the advantage of playing penhold.
Recently I have been experimenting with a shakehand chopping style using an extremely defensive blade (Zebrawood Oversize 3-ply). I like to twiddle to attack on the backhand, and Hurricane 3 on a defensive blade was simply not powerful enough to make dangerous attacks or lift heavy backspin. Even on forehand it left something to be desired. So I decided to try D09c again.
On this defensive blade the difference between H3 and D09c is immense. I can create fast balls with relatively little effort. Instead of feeling uncontrollable, the catapult effect gives a very comfortable increase in speed. This is exactly what I need to upgrade my hybrid-defense style.
When playing defense with Hurricane, I was mostly chopping on both wings, with the occasional topspin attack. These attacks were never fast or powerful enough to overwhelm my opponents, so I would only win points with good placement. Playing heavy sidespin loops far from the table was another main tactic of mine -- trying to imitate Hou Yingchao.
Switching to D09c makes my attacks much more potent. Instead of playing pure defense, I can attack when the ball comes to my forehand. My opponents are hitting the ball out because my loops are so powerful -- something which never happened with Hurricane. The backhand attack is also really nice, allowing me to kill the ball easily and get the ball safely over the net.
Aside from power, the other main thing I like about D09c is the high arc. When playing with an offensive blade I found the high arc to be annoying, but on a defensive blade it is quite nice. Particularly for lifting backspin, I don't have to exert nearly as much effort as with Hurricane. The motion for lifting backspin with D09c is quite similar to a normal loop with Hurricane. This can give me precious time during points to reposition and get ready for the next ball.
With Hurricane 3, blocking flat balls is a nuisance. You have to make sure to brush the ball to add your own spin, or the shot will be unstable. With D09c, I found that it can convert some of the speed of a smash into spin. It was possible to block smashes from short pips and antispin rubbers, and when the ball digs into the sponge it will generate some topspin on the return. Thus, I feel comfortable staying closer to the table and fast-blocking with my forehand.
Another big pro is how easy it is to generate spin, compared to Hurricane. With a small wrist motion, I can create 80% of the high end spin. This makes it easier to be deceptive about my spin and how much spin I am making. Needless to say, the high end spin is not as good as Hurricane's.
Certainly I think D09c improves my chopper playing style, transforming it from a pure defense style to a more hybrid defense-offense style. I am much more likely to attack and counterattack on the forehand, and much more likely to twiddle for a backhand smash. However, D09c still has some cons which I would like to list.
1. It is bad at chopping. I think this has to do with the throw angle and the catapult effect. Chopping on forehand with this rubber just isn't as stable as chopping with Hurricane 3. I am somewhat forced to attack balls that come to my forehand, because chopping might not be an option.
2. You cannot play passively or gently with D09c, you must play actively and touch the ball sharply. Touching the ball softly is a recipe for shooting the ball in a random direction. Therefore it is harder to carefully manipulate spin compared to H3 -- especially sidespin. For this reason I still think it would be a bad decision for a penhold player to choose D09c over H3, because H3 allows a much better short game and (side)spin manipulation.
3. Sidespin loops far away from the table are not as good. The quality of the spin is less, and they are harder to aim. Hurricane 3 allows low-to-ground scooping sidespin shots, but these are much harder to do with D09c. Side-downspin chops and snakes are also harder to execute. Best to just not let the ball drop so low, and just play pure topspin. I will certainly miss this aspect of H3, but I will keep trying to imitate it with D09c.
All in all this rubber feels amazing and after only one playing session I was already seeing improvements. I'm excited to continue using it. Hurricane 3 is nice and has a special place in my heart, but for a modern defender I think D09c is clearly a better option.
