I know very little about them but I have my doubts about using them for hunting. As you mentioned,fletch alignment. What if you bump your arrow? Will your arrow fall off? I do some still hunting and wonder how often I would be picking up my arrow. What if the tip of your arrowbumps a branch as your picking up your bow to shoot that buck of a lifetime? I think it could be great on a bow set up for target shooting. Also does it center exactly every time? could that mess with your accuracy. I strictly hunt and set up my equipment to eliminate possible problems.
