What Buckhunter said, but something in the .500 area is what is *recommended*

My wife is shooting 43-44 lbs with a 27 inch draw. Our bow guy set her up with Carbon Express's with a 250 spine.

I would take your brother to a local hunting store in your area. They have an arrow scale chart for each bow. They will give the arrow weight and size information free of charge.

This link below is for a bow set up.
Good Luck!

Mating an arrow with a bow is part science and part witchcraft.

To many variables to even mention. I suggest he purchase a test kit for the arrow of his choice and try them out with the desired head weight.
