Hi- I just picked up a "Classic 7 Pro" "fusion frame". Someone I know has one that looks the same, but says "C7 pro" "fusion frame" Anyone know the history of these? Whats the difference? When were they released? What are they made of, any info is appreciated..... So far I love hitting groundstrokes and volleying with the frame, but havent been able to serve for dear life (though I was playing a dnx 10 MP up til recently which I served well with?. Thanks much.
