I love it when someone comes up with a new innovation, as opposed to just making the racquets lighter and lighter. I mean, golf did the titanium and then graphite progression as well. This seems a bit more "radical".
I was in a racquetball club over the weekend and the new innovation in those racquets is that 8-10 mains extend all the way down into the handle. According to the guy working the front desk, that supposedly increases the sweetspot to the 90% range. Which I thought was pretty cool.
