OK, so the L13 is more understable than the Medusa. It always hyzers back at the very very end of it's flight, but extremely easy to turn over at higher speeds. I had some very interesting flights out of it, almost W-shaped starting from steep hyzer. These discs are kind of strange for power throwers, I would not recommend it for them unless for shaping understable shots that hyzer out at the end. But, for low power throwers, both the Medusa and L13 are great discs for learning how to turn a disc over, manipulate nose angles, and work different lines. I think it is especially great for ladies who aren't big arms, as a backhand finesse driver. It will, of course, reward lower power throwers for getting the nose down. It makes a great S-flight for people throwing ~200'-250'.
