Overstable with glide. I'm pretty impressed with this disc even though I don't have the power to justify using it most of the time. I picked up one (169g VIP) to mess around with not expecting I'd ever have reason to bag it for anything competitive. Winds gusting 30 to 40 mph today and I managed damn near my max distance, uphill, straight into the wind. As long as I was careful with if/when the wind got under the disc, I found it very controllable in conditions that at times had my King doing barrel rolls.
...there was a time when you were taught to find the best disc for you, not the best disc for your situation on the course, which is how they are sold now. IMO, the flight charts are basically there to point out all the stuff you dont have in your bag and why you suck.
