Threw a d2 for the first time today and it flew like a seasoned destroyer, I haven't seen any consistency issues with prodigy at all. Ive thrown 3 different m1s, all were the same, m4s are amazing, m3s are a touch overstable. D1 protos were kinda flippy but the mold was tweaked and my first runs are flying great. Ive thrown multiples of every mold and they are more consistent than any other company I've seen.
Funny, I've had completely different experiences with them. I've thrown a FR D1 that was like a pretty beat destroyer, and one that flew like a brand new destroyer. I've thrown a D4 that was extremely flippy, and I own a D4 that flies like the D1's.
All in all, I haven't found two prodigy discs of the same mold that fly similarly. They're all over the map, which is why I won't be buying any for the next year or so (at least)
