I tried it briefly, it was faster and harder than H2, but the rubbers were different (Tibhar K2), so I can't say much. It was ok, nothing really special, but that's me. If budget allows, I would definitely prefer a H2 to a So-Ten, between H2 and Acoustic inner - it makes sense to try both before buying. If you can not try them, in my view a H2 is a safer bet. Acoustic Inner struck me as a more offensive racket requiring a certain level of technique to maintain shot stability, H2 also rewards solid technique mightily and is geared towards a good player, but is more forgiving. Bear in mind the weight, a an 90g+ H2 would be quite a weapon, mine is 85g and quite soft. Also, the H2 handle is quite thin, and it is more squarish compared to an old Acoustic. G-Rev handle, I guess, is closer to H2.
