In my experience,(on hundreds of hog blood trails)an extremely sharp three blade is best. They are also super easy to sharpen, even for me.
Hogs are notoriously poor bleeders(smaller vitals and less vascular than deer).
I personally keep one two blade(a Badger) in my quiver in case I run into a truly big hog. The rest of my arrows have 3 blade Woodsman heads.
Bill Langer's son Ben (age 12)killed three hogs(60-75#) with us last year pulling 40#, probably less at his draw. He was using 3 blade Woodsman Elites and heavy carbon arrows.
I don't like to denegrate any broadheads but I've seen a pattern of lost hogs(and a turkey) with guys using big, WIDE, two blade heads. With any head,the goal should be to put an entry and exit hole so one can find the pig. The three blade tends to put more blood on the ground(again, in my experience).
