This speed thing has been the biggest difference between IBO and ASA for years. If you shoot the right arrows you can get the speed even with the short draw and low poundages. If your bow is not PERFECTLY tuned your arrow flight will be more erratic at the higher speeds however. I keep my bows at around 285 and can shoot both org, just have to check the chrony for the ASA shoots. The difference between 280 and 300 is so slight that you would have to be a machine to tell the difference on an average shot.
