Cossack,
Sorry you read something into my post I did not intend to say. I did not say the crossbow is not ethical, in fact I said it is my choice in the archery only portion of the fall season!
I also hunt most of the deer season with a crossbow, but in the few days of gun and muzzleloader seasons I use the guns because I feel they giveme better odds of dropping a deer quickly and cleanly.

Ethics (my definition)is not which weapon you choose, butyour (or my)choice of the available legal weapon you have the most confidence in for a humane kill, then making sure you limit your shots to only those that have a high probability of success.

As for broadhead type - the most accurate broadhead from your bow is the only choice! I can't tell you what will shoot best, you have to try your choices and see how accurate they are. A huge cutting diameter that misses the vitals isn't much good, but a smaller razor sharp broadhead you can put into asmall target every shot will kill any turkey out there, as long as you can put it where it needs to go! For my Phoenix that narrows it down to a couple fixed blade broadheads for me. I've had mechanicals open in flight, and fail to open on game, so I just don't trust mechanicals. The "grappler" is a good addition, but there's still a chance of a bird flying off and they would be very difficult to track "on the wing".

I'll hunt turkeys this spring with my shotgun. For you...... it's YOUR choice, and I'll not belittle you if you choose something else (legally allowed) for you hunt. In fact, I wish you a safe, enjoyable, successful hunt!!!!!!!!

Edited to add:
Cossack, in re-reading your response to my post I'm wondering if you read the entire post?
You quoted me as saying:
Then you accuse me of implying you're being un-ethical by using a crossbow!
The next line in my original post says:
Did you miss something there?
