The PT630 is the closest you are going to get to a PC600 that is slightly more forgiving. With proper stringing it can be even closer. The PC600 plays well with a vast majority of strings and tension but with the PT630 you need to experiment a little with different setups. I managed to "shape" a PT630 to hit like a PC60 at least on serve by manipulating the string tension, elongating the shape of the head by stringing mains at around 40 and cross at around 70.
As for high level doubles, neither of these two frames are optimal. There are other frames that volley better than the PT630 while the PC600 tends to frame some shots.
