BigJ... that's a very in-depth and fair review of the Hostage.
But this thread is about the Hostage Pro -- a completely different animal.

All your concerns and reasons you disliked the plain old plastic Hostage have been addressed with the Pro: larger hoop size (to accomodate popular high-profile fletching such as Blazers. That will also allow for a harder offset or helical as well), adjustable ramped bristles and CNC machined out of 6061 aluminum.
