This has become my hybrid fairway / control driver disc. I have a couple BaseGrip for understable and stable shots, and a DuraFlex for overstable. For my arm, it's a faster 400 F3 that compliments the FX-2 perfectly. The rim depth and "ridge" shape gives me better grip and snap on throws forehand and backhand than the H-series. When I break one in too far or throw one somewhere I shouldn't, it's simple and inexpensive to replace. I have noticed the swirly BaseGrip is more stable, almost DuraFlex stiff, compared to the non-swirly.
Loving the spot that the F model fills in and this one just adds style points. They feel good in the hand. Fly very nicely
