OK, I shot my second-ever 3D shoot today, and am really anticipating getting into this big-time over the next several years... I'm looking to participate in Hunter Class at the shoots I attend, and have just been perusing both ASA's and IBO's websites trying to bone up on everything... Let me make sure I'm not missing something. In ASA, Hunter Class is limited to shooting 280 fps; at IBO-sanctioned shoots, there's just a 5-grain-per-lb rule. At IBO shoots, you can only use 8.5-power binos; I didn't see a restriction at ASA shoots. at IBO shoots, you have to have a vane measuring at least 3.75 inches; again, I saw no restriction for this on the ASA site. It does look like one consistency between both governing bodies is that four fixed pins is the max, and the stabilizer has to be shorter than 12 inches. Please let me know if these findings are correct, and if not -- which ones aren't. If you've got a link showing where I'm wrong at, that would be most appreciated. Thanks!
