I am prefacing this post with me being terrible at describing flights using the acronyms, so I decided to spell it out. I have posted previously about this disc in various other places and feel that I finally have a handle on it.
I carry a g-line and c-line CD2 and have been throwing them pretty regularly each round. The G-line for me flies closest to the numbers out of box. I throw LHBH and have been releasing it very flat and noticed slight turn followed by a healthy fade, not drastic by any means, as to be expected. This disc overall is very straight in flight and has been fun to throw. When I have purposely turned the disc off the tee I can still get it fade back nicely. My hyzers are weak, so for me when thrown on this line it flips to flat mid flight and fades. This disc reminds me of a longer beaten star teebird. The CD2 in C-line for me is more HSS for my arm speed and does not have much turn out of box (although I can make it turn off the tee if wanted). For me it flies very straight and has a nice fade at the end of flight. I would compare it more to a longer first run FD or a seasoned c-line PD. The 3 C-lines I got were all extremely stiff which I think reduced the amount of potential glide this disc could have.
Some last random thoughts: I can throw my g-line further than my c-line, my c-lines held up in the wind better and I found the c-lines more controllable off the tee (especially in the woods).
I would like to get my hands on a stock run c-line to see if the came out less stiff. For me the Aussie open runs are the stiffest followed by the usdgc run. If anyone needs clarification let me know!
