Overdraw was the huge thing 10 years ago. Let me tell you, stay away from anything with overdraw. An overdraw rest is made so that the rest itself is set back from the bow's riser toward the bowstring. The reason behind this is to decrease arrow length, and therefore increase speed. They are not a good idea and here's why: You're going to lose a lot of accuracy.....bow tech is drawn out in a big way by using an overdraw rest. Ideally, your rest should sit directly above your hand. If you're rest sits behind your hand by a long ways, the left/right movement of your bowhand is increased significantly. Overdraws kind of went off the market quickly for a reason. They were a big fad a while back but have died off. I'd stay away from it if I were you, it'll cause you more pain than anything.
