RE: Which one would you choose for hunting.....
What are you calling high foc and low foc?
If I had my druthers,I choose an arrow that is VERY SLIGHTLY over spined with about 11% foc for hunting.
But,I can't argue with bumping above 20% and getting an arrow that is stiff(static spine)to shoot well and penetrate great.
I don't think that being between 15% and 19% is best though.These are just numbers and definately aren't set in stone,each setup is slightly different.
