There are too many variables to make a definitive declaration. Type of bow, draw weight, draw length, animals hunted, avg distance of shot, ability of the shooter, type of broadhead, etc. all come into play. So maybe look at it from a different perspective. Arguably the 3 most important considerations are accuracy, penetration and arrow flight or poi across a set of ranges. You can immediately throw out accuracy. If high FOC or heavy arrows were critical to accuracy, tournament archers would be shooting that setup and they dont. Weight can certainly be important for penetration but terminal penetration is going to be impacted also by head choice, tune, arrow spine, parts encountered on impact and movement of the animal, etc. It's a very dynamic metric to evaluate. So arrow flight, how much arch is in your archery from say 5 yards to 30 yards. It's pretty safe to say the avg shooter is going to be consistently more accurate in a hunting scenario when they cant always range the animal with a flatter shooting arrow. Add in to that hunting out west for mule deer or elk where being able to make a good shot at a longer distance may be needed but you are hunting bigger animals that your avg whitetail. This thinking is why I have always felt a moderate setup the better way to go for most compound shooters. Build the system around shooting the heaviest arrow you can and still maintain somewhere between 265-280 fps. This will make for a pretty quiet bow that shoots reasonably flat and an arrow with enough azz to blow through most critters in North America excluding a direct knuckle hit or spine hit. If you are only going to hunt whitetails at distances of 20 or less and you have the ability to properly tune a high foc heavy weight setup, by all means let the big dog eat. You may also have the ability to tune that setup and accurately shoot it out to 50-60 yards and if you can, get after it. Just remember you are not the avg bowhunter. The kid that is just starting to drive doesnt need a corvette and he doesnt need and F250 King Ranch, he needs something like a tacoma, functional that gets the job done. That's where we should all be encouraging the avg bowhunter imo.
