If you are going to use a 3 blade, that is a great choice. I have killed some very large hogs with them, but don't expect a pass through on a large hog unless you are going through the guts. Same can be said for a 2 blade though. Most times you get slowed down or stopped on the offside shoulder.
I would not be afraid to use that setup to go hog hunting in any situation, but if I was specifically chasing a large heavy shielded boar, I would opt for a quartering shot or use a 2 blade. BTW, those vpa heads sharpen up great. I have killed hogs with both head, and you won't go wrong with either a 1 1/4 or 1 1/8" head, but for large hogs I personally would chose the 1 1/8". No matter what you chose, the key to a good blood trail is hitting them in the right spot.
