I’ve used the Grizzly heads on and off over the past 20years. Kept going back to them when the bouble bevel heads I tried didn’t hold up as well.
Havn’t seen the new one out now, but the older ones were a pain to get sharp.
This season I’ll be using the 300gr Tuffheads. I like the size and material they are made of. They also come almost ready to hunt with. I’ll only have to touch up the edge to make them ready for my quiver.
