We are all lucky to be a part of such exciting times in the world of archery.
There's tons of R&D being done, as we speak, and I think it's largely due to the fact that the market is growing so fast, and everyone wants a piece of the pie.
Advertising, SELLS. And advertising, "big holes", sells.
We all know that friction, or drag, reduces kinetic energy, so therefore, the more surface contact area, the more loss of energy.
I'm not an engineer or scientist, but this makes sense to me.
Now.. my own experience... I've shot 7 deer with 2 blade rage. Got pass through on all of em. Shooting a 420gr. arrow, 60 to 65lb bow. All shots were 20yds or less. No damage to the head.
I'm not a rage salesman.. Just sharing results.
I think if I were going to shoot heavier animals, or shoot longer distances, I might think about shooting a smaller head. JMHO
