TGbow, how could you forget about the EF quiver? (Ha!) Just because we're not the biggest nor the oldest manufacturer, nor have the exposure of some of the other guys, you shouldn't forget us. After all, we have more variations and a wider range of bow quivers than anyone else.
We snug the hood and gripper screws pretty tight when the quiver is made. However, if you twist it to align the hood with the gripper, sometimes it will require retightening the philips screw that controls it. After that you should not have to tighten it.
