Hey sargi:
Just a heads up for you. If you change your broadhead weight you change your spine and thus your tune on your bow -- which every bowman knows your tune is very sensitive and absolutely critical. Besides a heavier broadhead is not necessarily a stronger one. Stick with your set-up you are comfy with and place your shot carefully. Be sure your blades are absolutely sharp. You can never have your blades sharp enough. Dull blades loose trophies.
