I think that if I had never played with Xiom Omega rubbers I would have the same feeling as in this review.
While I have a long experience with Omega 5 Asia and O5Tour, I"ll compare the new O7Asia to them.
Many things will fit with the review of yogi_bear, some may not, but you have to understand that Any review is a matter of personal feeling and evaluation.
The sponge of O7A is rated harder than the sponge of O5A, but because of the specifics of the rubber sheet it doesn't feel harder with finger pressing. O7A is lighter and my second Vega Tour blade paired with it is 4 gr lighter. As both my Vega Tour blades are 84 gr this reduction of weght is very sensible. During my first session I had very mixed feelings, but I know that these tensors need some 4-5 hours of just "hitting" before they get able to reveal their real character. So on the third session I started tpp feel O7A almost the same as O5A in AR over and near the table. The touch with it is with the same accuracy, but I miss a little the hinoki feel which is better with O5A. I didn't have to adjust anything in angle and power in this AR play. O7A has more spin than O5A and it is visible from the start with the first service. Till now I've played with O7A only with my son, he makes a lot of spin, but I didn't have the feeling that O7A is more sensible to incoming spin, I haven't thought about that at all, may be I'm just too familiar with his spin, have to check this with other players later.
At mid distance O7A starts to feel more different than O5A. With stronger hits it has more power. My deaper shots and those to the corners started to go out, so I had to adjust drive and angle, and in longer distance - the total swing. The O7A changes the arc of the trajectory faster and more unlinear than O5A with the inrease of power. The trajectory is going flatter, similar to O5Tour. Still the change of ball acceleration feels linear as with O5A. Stronger strokes with sharp topspin go with very flat trajectory, like they have no spin at all, but when the ball nocks the table, it sinks down with an acceleration, making it impossible to block and almost impossible to counter. Chopping is easy and a little bit higher than with O5A, but lower than with O5Tour. Sharper faster slices are easier too. Returning chopped balls is a little bit different than with O5A - over the table its almost the same as, slow balls close to table can be lifted the same way too, but lifting faster balls and attacking balls need adjustment - you need faster and longer vertical lift over the foreward move when lifting, and when attacking you have to take the ball earlier and to adjust the angle and/or the wing depending on distance and power. I don't think that its because of a more incomming spin sensibility, but because of the trajetory change with more power.
So up to now I think that O7A is a real upgrade to O5A. Its a little bit faster, has a little bit more spin, keeps the good feel and touch in AR and has some of the best characteristics of O5Tour. Once you get familiar with, it can be a dangerous weapon.
