For the past year I've been bagging a 3rd run C-PD, along with a Swirly S-PD. The 3rd run was bought new many years ago, and still flies just as stable as the day I bought it. I use it for my "overstable" PD shots, and also shots that need some skip. Very reliable disc that I know I can trust to not turn over.
The Swirly S-PD is also pretty beefy. It had become my workhorse PD, since I never throw the 3rd run in areas I may lose it. The Swirly is also a little less stable, so it is more workable on different lines. It's one of my go-to headwind drivers, basically it flies exactly like I always thought a PD should.
Last week I traded for a hot pink S-PD that came in a recent mystery box, and I bagged it over the weekend to see what it was like. My god, this S-PD is amazing! Not as stable as the other two I bag, but still doesn't turn over and has a nice reliable forward fade. I finally have a PD that "flies like a longer Teebird". I can rip into it with full power and get perfectly straight drives just shy of 400' on a rope, with a super soft fade. I think this S-PD is going to become my go-to PD for the rest of this summer.
