Easton ACC. No idea why I like them, but I do.
I recently shot a steel challange event -- one where you shoot through holes in steel targets until you don't -- and the ACC held up after banging steel. My field points (2) were bent all to hell, but the shafts didn't splinter. I saw mutilple other shafts explode.
FWIW -- I was shooting a Hoyt Carbon Defiant with a 29" draw at 70lbs. Targets were between 28 and 31 yards. Field tips were 100 grains...
