i use the carbon tech cheetahs. i really like them, they group very well and are quick little arrows, ive heard people doubt there durability, well tonight my father in law was shooting with me( he also shoots the carbon techs) and shot one into the strand board behind our target didn't hit the target at all( targets pretty shot up we can only shoot the edges now and it was too dark to be shooting ooops), went about 3 inches through from 25 yards and didn't put hardly a scratch on the arrows.
