Magnus stinger would be my choice. Another good choice would be Steel force.

I'd also look into the Easton AXIS or FMJ arrows instead of the larger diameter aluminum arrows. These two arrows have very small outside diameters that will also help maximize penetration. Install brass inserts in either of these two shafts to up your FOC to help the arrow recover better in flight and also help maximize penetration.

If you don't mind ordering your broadheads (assuming you might not have a traditional shop in your area) instead of picking them up at your local store then check out many of the "lesser known" l heads out there from companies like Alaska bowhunting suply, German Kinetics, Zwickey, etc...
