How Much of a Difference Does Weight Make on a Disc?

I know the heavier the more stable. What else is different about the flight of a heavy vs. light disc of the same kind? Anybody know?

I have a feeling weight also has a lot to do with psychology. for me, discs in darker color often feels heavy even if they are not. or some shapes and different disctypes or different plastic that have the same weight can feel more heavy than the other. that beeing said I drive longer with lighter discs. but its true that i feel the lightest discs struggle more in wind, but that is often when i throw too high :)
