MintDiscs.com says this about the Lobster:

"The Lobster is our first understable mid and one of the smoothest throwers on the market.
Beginners can spin it flat for tons of glide, and higher powered players will want to hyzer flip it for long controlled turnovers.

Approximate Flight Ratings: Speed 5 / Glide 5 / Turn -3 / Fade 1

PDGA Approved"
