Nossir. I haven't looked up the specs, but the Prodigy discs are both narrower in the rim width than a Nuke, Boss, etc. I have thrown both the D1 and the D4 some more. The D1 is similar in stability to a Z Force. Maybe half a point less HSS, meaning it fill turn some in a headwind. It is also somewhat faster than a Force. The plastic is really nice. The D4s are flippy, but fairly reliable in calm conditions. They haven't turned into rollers with no wind, or tailwind. They flip up, and have great forward glide as they track right, and given height or tailwind, come back, a long, long ways away. I have experimented with throwing them intentionally low with hyzer, and they don't have to have lots of height to fly straight. They can be thrown for long hyzers too, given good form. I remain impressed with both molds, and look forward to the others.
