DesertDude, I'm with you. I either shoot 125 or 145 grain broadheads, depending on which bow I'm using. I shoot 55# or 65# hunting bows and have found that arrow performance is very acceptable as long as it is tuned well. I have never been a great tinkerer, so fiddling with the FOC, adding weights, etc. just does not float my boat.
Maybe if I hunted the very large or dangerous game, I would re-think all of this, but with the whitetails at the distance I shoot, I already get plenty of penetration. You can only get two holes with a single arrow, one going in and one coming out the other side. The "standard" as you refer to it works just fine.
One other thought, I just may be too simple minded to grasp all the technical stuff.
