I got my first throws in with my two PDX's yesterday. I was surprised at the results. I got one S-line and one C-line, both max weight.
Like previously mentioned, the disc is fast. But what surprised me was how much glide it had. I was expecting them to be very beefy, but actually they are very workable and found I got really good distance with them.
I was a little disappointed at first because I was expecting them to be super stable, but I think one may stay in my bag due to the glide and distance I'm getting from them. And just like a standard PD, they seem to power down nicely.
Compared to my C-line PD, the PDX definitely is faster, and has a stronger fade with more skip at the end of its flight. But the HSS seemed pretty close.
I'll get to know them more once I get some more throws in with them. And if I find I really like them, I'll then need decide which one to bag.
