Well I have the original Hostage and LOVE it! With the pro you get adjustability so you can fit the diameter of your arrow perfectly, smaller brushes, and more clearance for your vanes. I shoot blazers and they never hit the outside at all and I have no complaints on the hostage. It's just important that you line up your vanes well so they pass through the gaps in the brushes. It's a little easier finding replacement brushes for the pro but you can find brushes online for the hostage. If you hear a lot about the brushes wearing down fast don't worry about it, as long as you tune your bow right it'll be fine. I've had mine since January and shoot quit a bit with no problems with them getting worn at all.
