Haha see, that's what I was looking for in the PT630! Maybe I got a dud frame, because I definitely have a lot of shock on mishits.
That being said, I can't use wood rackets at all. The low flex absolutely kills my arms!
I guess the real solution for us is to miss hit less hahaha I am not sure why yours does not feel the same the only explanation is that u have 280 and not 630 lots of people think it'd the same racquet but 280 is stiffer and slightly harsher on anything but sweet spot.
