Nice comments above Jack.
You nailed it in point 5. I prefer an aggressive game and the P1 has amazing put away power. For its stock weight and SW, it excels.
As far as the gap in racquets that you are referring to, I had previously filled this gap with a leaded 400T. It offers similar results to the P1 with a lower net SW (around 316) after modifications. After testing the P1, my 1st inclination was to bring up the SW on the Dunlop, but I ended up taking the easy route by selling them and buying a few more P1s.
