The weight of the broad head depends on what spine arrow you have no use putting a big head on an arrow that is borderline weak.

I use a Muzzy Phantom SS200gr broad head connected to a Beman ICS Hunter 400 spine 28" arrow with 4 Duravane Predator fletches for a FOC of 23.8% out of my Black Ice set at 59lbs 28" draw.

I usually start off with what size head I want to use then build an arrow around it so I end up with a perfectly spined arrow.

I take out the 2 bleeder blades which gives me 200gr.
