I see Pro Kennex came out last year with a new racket - the Kinetic KI Q5 (315G). Someone wrote that it's an updated version of the Pro Kennex Ki-5. I have the Pro Kennex KI-5. I bought the KI-5 before they changed the paint job on it. I like the KI-5, but feel it is underpowered. I am wondering if this new racquet - the KI Q5 - has more, less or the same power as the KI-5. (I use soft multifilament strings in case that's a factor).
