Threw one of my 10 yr anniversary CPDs in the bag for my rounds today. For reference, I have never thrown a CFR PD, but do have a good bit of experience with the 3rd runs, which I love and compared the 10 yrs to.
First impressions: the 10 yrs are crystal clear, high PLH, and flat. 10 yr PLH is higher vs a 3rd run. 10 yr plastic is softer/ grippier, but by no means soft.
For me, the 2 CLines I've mentioned above give me the same result, but they go about it a little different. Neither really think about turning. The 10 yrs carry a bit more, and dump a bit more. The 3rd runs don't glide as much and the fade goes forward more.
I think the 10 yrs are great bookend CPDs. The flatness really works for my FH. If you already have a bunch of beefy PDs, you're not gonna miss the 10yr. If you need an OS PD these will do the job, and I guess by extension the "stock run" of the same vintage.
