FMJ's are great shafts, and I do shoot them. They are very durable with impact shots, however, I don't like how they tend to bend.
I had one bend just shooting at tennis balls in my backyard. Plus, I've killed 5 deer with them, and each animal either broke the shaft, or on pass through shots, the arrow was too bent to be used again. The arrow did its job, so I can't fault it for that, but I just expected more from the arrow at that price.
I also like how they pull easily out of targets.
However, I believe the Easton Aftermath to be a better value. All carbon shaft, that is durable. Probably not as durable as FMJ with impact shots, but they don't bend.
I have multiple arrows that have killed multiple deer. Clean the fletch off, and its ready to go again.
Just my two cents....
