As a disc I never really got on with the envy. In the eclipse plastic it's definitely very overstable, with enough torque resistance to maybe take a 70% power forehand without really starting to turn over. My main issue was that it flies too fast for me to feel like I had much touch with it, limiting it to a driving putter role that I didn't often use, and that's mainly why this is 4 stars. The eclipse plastic has great grip to it though and the glow is fantastic in terms of brightness and longevity.
