I have been playing TG2 for the past 12 years with Red, black, Neo and regular versions and different thicknesses and hardnesses, and I decided to try the blue sponge province TG2 a few months ago. I had the 39 Degree 2.2 and i didn't like it at all. The top sheet is not tacky enough, the amount of tack is similar to hurricane 8 which I also don't like. The blue sponge on a regular H3 would increase the dwell time but with the TG2's firmer top sheet the effect is minimal, and the power is less than the older commercial orange sponge versions. So the overall impact is the power/spin of close to the table drive is significantly reduced, and the margin for error is small because the ball will go right into the net when you are a little out of position (which happens all the time). Serve/receive is also harder due to the reduced tackiness.
I tried using it with W968, Fang Bo and Fang Bo X and the only blade that makes it somewhat playable is Fang Bo X, but only in practice. It's not good for games due to all the issues mentioned above.
I have also noticed reduction of tackiness of many rubbers from DHS, and the only ones that I like now are province and national H3 which are still tacky as before. They can lift a ball up at least a foot when facing down, and the newer TG2 and H8 can only lift up like an inch.
