I've heard some people compare a Wasp to a KC Pro Roc for stability...I guess they're similar, but I think that Wasp is a tad more overstable. If you're looking for a pig in the wind then the Drone - like others have said - is a great disc for that. I honestly throw all three of these discs and love them, they're a staple in my bag.
Just pulled out a new KC Pro Roc 175g and a brand new Z- Wasp 174g and threw them into a mild headwind. The KC was more overstable consistently, but I still think the Z wasp would be more overstable as it will hold it longer because of the plastic difference.
I think when they made the wasp it was to compete with the roc...get a flat top one like everyone has said and it will fight the wind. The FlX Drone and Z Drone are both crazy overstable...you will definitely get more "D" out of the wasp...although you should pick up a drone too just because they are great to have as well...it's all about "The Hive"
