RE: carbon arrows for hunting and 3d.
I bought Carbon Express 3D Selects 300' s for hunting a year and a half ago. I chose them because they' re straight to .001 and weigh 8 grains per inch. My arrow flies very flat (very good for 3D). At 28 1/2" with feathers and a 100 grain tip it weighs 350 grains. I shot two deer with them last fall and am still shooting both today. I am going to start shooting 3D so I guess I' m all set. Very happy with the arrows!
