You will not need to shoot heavy tackle, in fact arrow placement is your best friend, next to a really sharp broadhead. I have killed dozens of hogs all with archery gear, so here is the real deal, if you are shooting draw weights in the 40 to 50 pound range, get a strong, razor sharp, two blade head. My fiancee' shoots in the 40-44pound range shooting a couple of custom made longbows, killing hogs are not a problem for her at those weights, nor is penatration. We both limit our shooting on hogs to the typical 15-20 yard shots, not because they won't do the job at the longer ranges but because arrow placement is so important.
The area of impact on broadside shots for hogs should be right above the elbow of the shoulder or right at the angle of the shoulder. If you don't believe me, go to
www.texasboars.com, they have a real hog that shows the cut away of the sweet spot. Shoot a hog like you would shoot a deer, and you will be feeding coyotes, and the like. The guts come forward darn near to the shoulder, while a quartering shot is one I won't pass on, it is by no means a requirement. By the way, we do most of our hog killing from the gound, I think it provides the best angle for a good killing shot.
So if you just want to shoot a heavy bow go ahead, but most people I know that are hog hunters are laying them low with well placed shots from bows 40 - 60 pounds of draw weight. Oh! just make sure you get that arrow weight up, the FOC correct, and a sharp broadhead. If shooting below 50 pounds I would suggest you stay with a two blade cut on contact design, if over that, any of the three blades such as the Woodman, MA3, being my favorites, or a snuffer.......
