Hmmmm...I have most of the current traditional heads 2, 3 & 4 blade, double and single bevel. All are great.
I have killed the most things with Zwickey 2 blade Deltas. Easy to sharpen, silent, inexpensive, durable, fly good; very traditional & 'historic'. Have also killed a bunch of deer with Snuffers. Most frustrated with Grizzlys (Zipper Kodiaks now) on deer but have still have had success. I believe in the Grizzly concept but question blood trail effectiveness for deer. Many examples to prove me otherwise though.
Buck in my avatar was killed with an Abowyer Wapiti. One of my favorites.
Too many to choose from actually but also liking the Big Game heads by Centaur and Simmons Tree Sharks but haven't killed anything with either...yet.
I could hunt the rest of my life with Zwickey 2 blade Deltas...all things considered.
