I completely agree with ControlledSpin's review. I am a two-winged penholder with a USATT rating of 1650, and I was using the Tenergy 05 on my backhand. With the Tenergy 05, I could not commit to a full backhand proper stroke because the rubber was too bouncy and hard to control. With the GoldArc 8 (47.5 hardness), I feel more confident with my backhand loops. I recommend this rubber if you feel that the Tenergy 05 is too hard to control for you. If you are comfortable with the Tenergy 05, I think you should stay with it because it is faster and has more spin.
