I am sure you can find more but ASA has shot gun starts for the most part. ASA has a slow speed class with the exception of the new OUTLAW CLASS {available in only a few test states this year}. If you shoot ASA you will have to make sure you arrow is not traveling faster the 285 FPS. Both IBO and ASA have some great guide lines / rules and both of them could learn a little from each other. The IBO has been way more interesting for me threw the years.I do sort of like the 14 ring thing in ASA .. Its a daring shot and anything that make 3D more fun I am for.
