What is this racket like? Looking at the specs, it seems to have a very similar weight distribution to the PSC6.1, am I right in thinking this? How does it compare to the PSC in other regards, I don't think it is as stiff which would be an advantage for me. Anyone got a good opinion on this frame? Also, there is a review on TW for a Wilson Tour 90, is this the same thing? The specs seem to differ from other places.
