RE: Total arrow weight
I shoot a hunting (whitetails) arrow that weighs in at 462gr.
I don't see me shooting over +/- 30yds, based on the type of hunting I do.
My set-up allows me to take advantage of the heavier arrow without a concern for arrow drop at those yardages. It's why I shoot what I shoot.
Blanket statements, without regard for individual circumstances, are useless (in my opinion). Go with what works for YOUR circumstances.
