Magnus Stingers and SteelForce heads I have seen do wonders on deer over the last 3 years. Both are scarey sharp and fly like darts. Magnus has a lifetime guarentee and SteelForce will resharpen for you. The reason I shoot Magnus is I can shoot the exact heads I am gonna hunt with right up to the night before I go out and then just change the blades and be ready with razor sharp heads that I KNOW are flying perfectly from my setup.

SteelForce heads definately get the nod from me as well though as I have seen my brother and best friend get passthroughs with what would not be considered high power setups.........my brother even destroyed the spine of a buck with a SteelForce head on a shot he yipped........so they are damn tough heads as well.

Good Luck.
