Lord have mercy, I think my points weigh what your arrow does. My arrows run 1700 or more grains at 38" and I draw 80+@36". It's a full Manchu hunting setup. I've dug a foot of arrow out of the ground after it went full through my target. A 76# bow of mine with a similar setup put an arrow through both sides of a car door and dimpled out the metal on the outside of the opposite door.
For your setup, finding a few more grains up front will help you, as you're gonna need the EFOC. Getting it to 10GPP with point weight ought to get you an arrow that will drop anything in the US. Your setup is plenty efficient, but I think those few extra grains won't go amiss. I shoot mine just as much for historical preservation as I do because a 36" draw is standard for the equipment.
