This is a question where you'll get as many answers ask responses. Truth is, there are a lot of very good Single Bevel heads on the market. There is no one best for everybody.
What I like, you may not, same with Bows, Arrows ect.....
This is a very personal sport.
I would suggest you try a small sampling of several heads listed here and decide for yourself. Some come hunt ready,
Maybe what your looking for, some require putting a final edge but are half the price.
Gotta love this site though, you will definitely get some opinions.
