RE: Fat Shafts
Jeff, I don't think you will have anything to worry about unless you plan to go to nationally sanctioned NFAA competition. Likely any 3D organizations that will follow will not put these into effect until the 09 season anyhow, they won't likely make a change mid season.
If the 3D and Indoor/Field organizations do make them illegal, watch GT make some absolutely fantastic leaps and bounds in technology now that they can invest some real $$$ into tool sets without the worry of a newer bigger size from a competitor pushing the envelope, with them being forced to play "catch up" with their R&D dollars. I'm betting if we see all of these changes come into effect for 09' we will see GTcome out with a 23 series aluminum/carbon with their pin nock components.........then we will have arrows with superior tolerances of aluminum, durability of carbon, and more than likely to spine better than most of the fat carbons that are out there now. I've got my fingers crossed.
