I had two problems with the dozen black shafts I bought. The first problem was that anytime I had the slap together at the target they dented, I know this happens but in only three practices I had lost a total of 6 arrows and the other problem I had was they cracked at the insert, the inserts fit well I put them in myself so I don't think it was a problem with inserts but who knows. To make a long story short with in five days I had 0 good shafts.
So I decided to try the easton epic shafts and I bought a dozen shafts and I have had three brake one was on a deer and the other two were a robin hood<img src=icon_smile_big.gif border=0 align=middle> the kind of problems you like to have<img src=icon_smile_wink.gif border=0 align=middle>. I have had the easton shafts slap together just like the blackhawk and have had no problems. Maybe I got a bad patch, but at the shop I buy from there has been many arrow bite the dust just like mine did so they no longer stock them.
