This (commercial version) is one of the best forehand rubbers for me. I'm playing strokes with full body movement, and brush looping a lot, aiming for turning most back spin balls with a powerful loop.Now I have tried a lot of forehand rubbers in various hardness degrees. But I tend to return to my H3N, now in 41 deg 2.15mm. This rubber is superior in spin. The harder, catapulting sponge gives the perfect kick when spinning the ball, in any way. When I compare the H3N to harder non-Chinese rubbers, these rubbers (when looping) works good, if your strokes aren't that fast and you don't hit the ball thin (brush looping). There isn't really that much more to say about this rubber. This is my reference rubber when trying out new forehand rubbers. The ones that gets near in performance is: 729 Battle II Provincial Gold 40 deg, Yinhe Big Dipper 38-39 deg and DHS Skyline TG2 NEO 39-40 deg. These are very spinny as well, but not that much catapult, better control and a bit less speed. Don't misunderstand me. These are very good rubbers, but a little lower in my rank. Yinhe Moon Pro Hard is a rubber that comes near in speed, but perhaps it lacks a bit in catapult and spin.
