I initially saw them and thought what an awesome design.I liked the design and feedback on the snypers from last year a lot and thought these must be even better. Now the guys that are getting their initial shipments over on that other site are saying that the blades don't stay closed in flight and thereis more than one person claiming this...................I don't know if there is any merit to this as I try to take everything I hear about this industry with a grain of salt. I like the design of these heads still, however if more reports keep popping up of the blades opening prematurely I think I would rather shoot the regular old school snypers for my expandable head this year.
