I've been playing the Duel G97 for a while now; I have both the 310 g and 330 g versions.
It's always difficult to relate to descriptions like "power" and "pop", as we have different perspectives and references. That being said: I've been through a great numbers of frames over the last few years, and to me, this is the best compromise so far, if your prefer thin beamed player's frames. I thought I had found perfect frames in the: Textreme Tour 95 (lacked power), RF97A (too cumbersome/clubby) and the new Pure Strike 16x19 (too stiff, too Babolat'ish and too tweener/hollow-feeling). The DG97 has been a great compromise among above.
It doesn't give me the (feeling of) free power and pop of the PS, but even without actual measurements, I think a major part of this perceived difference is just that: a feeling, and not necessarily one that translates into mph and rpms.
With good weight transfer I have no problem to generate good pace, and whilst both the PS and RF97A f.inst. had somewhat more to offer in that department, the 16x20 pattern of the DG97 offers me better control. One frame that offers a both power and control is the Pure Strike Tour; but that was too stiff and a little too flat for my taste, but a great attacking frame, still.
And the feel of maneuverability is several notches above, due to the thin beamed frame.
