Imo M1 is a between a hornet and drone with better glide than either. The M3 is wasp like, no turn really and a very abrupt fade. M4 is like a buzz ss or a beat buzz. Meteorish, but it feels smaller in diameter and height, not sure how accurate that is in reality tho.
So far i havent thrown any prodigy mids that have the qualities that dx roc throwers look for. In a base/mid grade plastic the M3 would be pretty money tho.
