I currently have a Arizona Archery Lightning Magnetic Fall-away Arrow Rest and love it but could see ways to improve it. I've noticed that a lot of competition bows have blade styles rests. Can someone explain to me why these things which are simpler than a prong rest cost soo much and are used by many target archers? I always thought the drop away rests were the best so I was wondering if i could put one of the blade things on my rest and then it will also be a drop away. Will this be better than either separate or is there something that makes a stationary piece of spring steel better??
