I got a chance to shoot at Nelsonville for the first time this year, and let me tell you I am glad i did not forget or lose any arrows there! All the vendors there were selling arrows with Blazers on them, I didnt see any fletched up with 4" vanes. I think the IBO should not worry so much about the vanes people you as much as the other equiptment they use. I saw alot of fat shafts and target bows in Hunter class. Why not drop the vane rule for a 400gr. arrow weight rule??
