To be more help I need to know your draw length.
I am not sure of the acceptable FOC.From my experience it doesn't seem to matter too much.The only thing is that if you shoot an arrow too heavy and you miss judge the distance,it will drop much faster than a lighter arrow.9-10 grains of arrow weight per pound of draw weight would keep your bow safe and be plenty heavy to hunt Deer with.That is guessing that you draw 27 or longer.
My wife shoots 600 spine from her bow with 175 grn tips.that is a lot of FOC but it doesn't seem to matter.She doesn't hunt though, so it isn't as important that she have a flat shooting rig.
When you set up your arrow you need to think about the broadhead you will use to hunt with.You don't need to shoot heavy field tips if you will be useing a light broadhead later.Or the other way around.
