Anyway, I'd just like to hear some opinions sprinkled with some facts.
There's a good quote! :D
I've been shooting the Tuskers a few months. Very impressed so far. The big 190 Concorde is my favorite at this point. I like the versatility of the head, the single blade piece makes it pretty easy to sharpen however you want to do it. Right, left or double bevel will all work well with the head. They fly super and take and hold a great edge. They seem tough enough to me thus far that I'd tackle anything that walks with one on the front of my arrow. Those were opinions...
Now for some interesting facts. I don't think all your data is correct. The Tusker is certainly not double the thickness of a Grizzly 190, although it may have a slight edge. A standard Grizzly 125 is .040 and the Grizzly 190 is substantially thicker than a 125 if that helps you any. Both the Grizzly 190 and the Tuskers are reportedly hardened to about 52 HRC, although recent Grizzlies have seemed to be even harder. So on hardness it's about a tie and the edge probably goes to Grizzly. Tusker wins on being easier to sharpen than a Grizzly, and can be used any way you want while the Griz is limited to right wing fletching for best performance. You are absolutely correct the Grizzly has a smoother ferrule, but I've not found the ferrule bump on the Tusker to be quite as dramatic as pictures suggest. There's not a whole lot of bump when you run a finger over them, much less than say a Hill for comparison.
I've hunted them this year but have drawn no blood. Granite Mtn you are the man! Great experiences thanks for sharing.
Unlike you, I can get single bevels sharper than anything, so I tend to single bevel almost all my heads no matter what they are.
Good hunting all! Tim
