Hunting hog and wild boar here in NC is very different from that in TX. Often times you will not get a head shot, and there are times when you are not allowed to run dogs, in some counties you aren't allowed to at all. So sometimes you need something that can reliably punch through their armor.
With all due respect Sir, that's about like saying that Deer hunting over there is very different than it is on this side of the country. Either way, shot placement is key. A larger arrow weight accompanied by a heavier draw weight on a bow is not needed on one side of the country for a specific animal versus another side of the country. If you can place your shot and put it in an effective area on the animal, it shouldn't make a difference what side of the country you're on.
If you're hunting a pig, it's just the same. Shot placement rules wherever you're at.
