Roadrunner, Monarch, Wraith and Beast are pretty close to each other. Skeeter kinda encroaching on buzz. I've become a Roadrunner fan recently, its more overstable than you would think and replaced the wraith for the shots I would use it on.
This is mainly because the wraith was a big flip disc for me, and I use the boss for my big S curve air shots at the moment. I'd say to ditch the wraith and others for the roadrunner unless you can't quite get the boss to S curve, since that looks like the more stable domey production run. If that's the case then the wraith will fade out of the S curve more than a roadrunner, so the wraith wins for the big flip S shot.
I throw Terminators when nobody looks.
