Check the Saturday sale over near Pryor, I think that is kinda close to you. If not let me know and I will get you some.
As far as the downside of the wings is they don't really translate well into real birds. They are too easy to chew on and don't really teach proper hold ect. In these early exposures your goal is to build excitement and drive, wings don't compare to a live bird flopping around to spark prey drive.
