400 is Prodigy’s grippy premium plastic, the blend in the same class as Innova Star and Discraft ESP. Semi-translucent, durable, sold on grip when wet. Nineteen moulds are listed in it.
That’s the all-conditions Prodigy plastic. It keeps grip in the rain and stays workable in the cold, and it holds flight for a long time. 400G is the same plastic with more glide by Prodigy’s account, 750 the firmer sibling.
It beats in a little faster than 750 and it isn’t as stiff. For a firm feel, 500 or 750.
