Dnk........Kinda bet that pic is not of someone using a carbon off of a crossbow, unless he a candidate for the Darwin award, "probably" off a compound and you said you use carbons off a compound.Soooo where does that leave you???????...............Once in my shop I had a customer using Nitro Stingers(junk) and the front sight was not tight and slid down, resulting in a collision with the arrow, arrow broke in half the rear half entering the(left) forearm and exited the wrist(sorry no pics) too busy trying to save his life when he took out 4ins of the artery......Wish all my deer bled that bad..........................Still have not answered why Easton does not guarantee their alums to stay straight???????And when was the last time you shot 10 deer with the same arrow??????? There is only "one real arrow " and that is the GOLD TIP(STRAIGHTNESS .001 weight tolerence+or-2grs)
