I finally pulled the trigger on two matched P1s (16 by 19). I'm just so amazed at how much better I'm playing. I beat one of the best 4.5s in the city in our last team match. Hoping for more success and barring injury (sucks being 42), I feel a great spring singles season coming on.
As far as string, I can't find anything better than Tour Bite 16L. And, I like this stick with the 5g buttcap the best.
This racquet does have some qualities of the PS90 (it has plow and all court capability unlike the Rad Pro (has plow but just yuck at the net)..).
