I bought a 166g D1. It's an overstable beast, but the plastic is great. Very tacky and easy to hold. It hasn't slipped out of my hand early... yet. It's a really nice disc for the "too fast and overstable for me so I can throw it into a strong headwind" slot in my bag. Works nice for thumbers that move to the right also.
I really like the plastic. I won't buy another Prodigy disc until they release fairway/control drivers though.
