Down in weight = any disc = less stable
Ill will definatly have to disagree with this statement.
i have thrown some fairly light discs and they were more overstable then the heavier ones
163g dx firebird the thing was more overstable than my 175g Champ Monster
158g Champ Orc would not flip when released flat, my 174g orc on the other hand will turnover when released flat without much effort at all
