Here's the real test: Draw your bow and hold for 90 seconds, then see how accurate you are. For some reason, most people worry more about pulling back the bow than holding it! I saw a show once where this guy was hunting elk (it may have been Ralph Cianciarulo) and had to hold for about two minutes. It hurt just to watch him, but he made a beautiful killshot. After the shot he almost collapsed, saying that his arms were on fire! If you can hold and shoot, you can probably crank it up...But do you really need to?
