I shoot these arrows indoors for spots, as well as the very similar CX X-Jammers. They are a heavy, STIFF, arrow that is most suited to spot shooting. I cannot imagine anyone shooting these for 3D or Field..they are just too heavy and slow. If you are looking for a large diameter carbon for 3D and have the draw length and poundage to get them up to speed, the GoldTip UL X-Cutters are the way to go.
