I would ask what is your budget first. Second I would increase broad head weight and FOC. 200gr upfront works wonders! Several ways to going about increasing the FOC.

Broad heads I like and have had good performance with are in no special order:

Razor Tricks
Iron Will
WASP Sharpshooter Traditional
Valkyrie Bloodeagles
Day Six Evo X


Eat Fish, Wear Grundens, Drink Alaskan.
