Dignics 09c is 100% more durable than the tenergy series, and more spin as well. Its better than tenergys for forehand flicking, but backhand flick requires more feeling and timing. Dignics series is also noticeably more controlled and better for blocking than tenergy. For me, Dignics has more speed than tenergy. I feel tenergy is a bit slow when using more power. Also tried D09c on a wood blade, its a bit too slow and I would reccomend using a carbon blade. To bring out full power of dignics, you need to hit with the right timing, or you get a awkward shot.
For Dignics 05 vs D09c:
Out of the package, Dignics 05 is tough to play with. Out of the package d05, is really hard but plays good after a few days. For d09c, it feels great out of the package but the arc needs some getting used to. Dignics 09c and Dignics 05 are both great for blocking.
