Dennis had some of these @ the Friz. There is the regular Raptor and the Raptor X. I picked up the Raptor X. THe plastic is very grippy and feels very durable. It is supposed to be the more stable of the two. It has a very flat top and the bottom feels similar to a Flash. After throwing it about 10 times I established that it is very fast and pretty understable.
I tried one of the Raptor protos when they first came out last year, And I'll agree with the Flash reference. It kind of felt like a gummy Flash, but flew like a really beat, less versatile Flash.
