I have a 28.5 inch draw, shooting a 70lb Mathews V3. I use a 16g HIT, 10g collar, 125g head. AAE max stealth 4 fletch. TAW is roughly 505 grains.That's really not a bad way to go at all, I just can't quite get where I want with total weight up front for hunting with them.
What arrow and point weight do you run?
That being said, I would consider lowering my point weight and switching to a 50g brass insert and cutting my arrows a little shorter to keep my weight around 500 grains. I like that weight, I get 265 FPS out of my bow and good penetration.
