the issue of course is that there will be a weakness, which only shows itself under a load- I've seen it happen....and it's usually the bow hand that pays the price - with the broken shaft pushing through your bow hand ....it's not pretty....and I always make stakes for my wife's bushes out of any shaft that demonstrates a funky grain.
Of course, I have hundreds and hundreds of shafts from the old Acme premiums I used in my arrow business ages ago- and didn't pay much for them in the eighties and early 90's.
The issue now is good quality POC is difficult to find....but is it really worth taking a chance on missing an animal, alerting a big buck, or injuring your hand in the middle of the season?
