After doing about a year and a half of research, I switched my setup this year to hunt moose. I chose the Easton FMJ .340 with inserts JB welded inside, and a 225 grain Tuffhead with a 75 grain titanium adapter. I've been shooting/testing the FMJ arrows for about 6 months and have not had a single one bend. I'm not saying they won't bend, just that it hasn't happened to me (knocking on wood as I type that).
I have not given up on wood arrows, and never will, but I want the best arrow/broadheads combination I can muster for such a large bodied animal, and the setup I mentioned above is what works for me. Someone might have different results, but we owe it to ourselves to find the best equipment for our Bowhunting needs.
