Years ago I got a set of 2219 XX75's (camo) I fletched them up with 4 5" parabolic orange feathers, an orange nock and Magnus I... actually it was long ago enough that Mike Sohm was still milling slots in Zwickey's to take a bleeder and those were the first heads on that set.
Being the kind of guy that retires his arrows after they make a kill, I was gettin down to the last 4 arrows in that set and realized I had 7 perfectly straight (though bloody)arrows just layin around.
I cleaned and refletched where needed and put those kill arrows back in circulation. I have no idea how many critters I piled up with that set of arrows over the years until I'd finally broken or bent all of them. Don't know how many times they each got recirculated either.
I've still got one straight one in a place of honor.... hmmm!
The '19 wall thickness is gonna outdo the '12 every time.
