FWIW, one of the worst bloodtrails that I have ever had was on a well hit TX hog that I had a complete pass through using a sharp Big Jim big 3 broadhead using my 82# morrison ILF. The hog was found around 150 yards away, but not soon enough to save the meat. There are no guarantees what will happen on a big nasty boar. I understand someones concern, especially when shooting low weight/energy setups. For the vast majority of hogs, the type of broadhead that you use won't matter for penetration reasons. I have shot plenty of them that I have not had an exit wound, or passthrough. I am pretty sure that I would rather have a big entrance wound where the arrow gets stopped on the offside rather than 2 small holes, but some may argue. A larger entrance hole may be less likely to plug up, but that will not always be the case. Simmons heads and 3 blades usually will do a fine job, but really if you are persistant in your tracking and put a good hit on them, just about any head will do. I don't know that there is much reason to get your blood pressure up on the issue, or be kinda snarky to other posters.
