I'm actually reassessing the APD. Off the bench, the PA has a higher SW, like 13 points higher. My problem is that to control the power and get a decent amount of time out of the strings, I have to go with 56lbs and 16 gauge strings. this ups the sw to about 330 and starts to make the racquet feel pretty harsh. That in itself isn't bad but get's a little clunky and then I have to tail weight. All fine but now I'm getting back to the weight of my Pro-staffs which actually feel better and are a bit more head light. AND, I'm having some issues with consistency with the PA. I'll hit a forehand and be like "wow, that was amazing" and then hit another that will hit the back fence..and be scratching my head wondering what just happened. I find the sweet spot...vague with the PA, which has me playing tentatively and going for larger targets. That's not really my style, I'm a bit more of an attacker and I LOVE hitting angles. With the APD, I know what is going to happen as soon as I hit the ball, even more so with the PS-97. With the PA, I cannot really tell.
Don't get me wrong, the PA hits a really mean ball. It's HUGE. Currently, I haven't figured out how to control it. time will tell
I weighted my APD with about 4 grams at 23" and close to the same in the handle. It's helped with stability and swing weight without making it feel sluggish. I started at 12 and worked my way down until I felt like I had a good balance between plow through and whippy-ness.
