I haven't shot that many but shot 2 this year and both had the best blood trails I have seen yet.  I was using a A Bowyer 300 grain AD total weight 760 grains out of a Centaur 53#.  Very impressed with the A Bowyer.  One was a little pig sharp quartering away angle ended up in his lower jaw bone and only went 30 yards.  The second was a 155# sow that went 28 yards.
   

Well I know that he has both trad and compound hunters and also know that he does not allow expandable broadheads.  He is a trad shooter himself and I think the stats were for trad hunters.  We managed to recover all our pigs hit with two bladed Tuffheads that hunt but one of John's took the better part of the day.

The key to any blood trail in my opinion is the exit wound.  I could care less if the arrows passes through just give me an entrance and exit.

So if you have enough bow to push a quality 3 blade through both sides you will bring home the bacon more often then not.

Very interesting Mike, thanks,
What would you consider enough bow? at what draw length? for say 200# and under.

I usually use woodsman's and have put down a few hogs with them. They get my vote.  

300 xtremes here on every pig I have killed except 2 and those were 4 blades.

I've killed a bunch and have never used anything but 3 blades.

Woodsmans and Snuffers at first....but ever since I was sent a prototype VPA 3 blade before they were even on the market....I've never used anything else!

I've killed them with glue-on 160's on steel adapters, screw-in 250's, and 1 1/4" 250 screw-in's.

Here's two from last spring with 1 1/4" 250's....

And 2 from the winter before, 160's glued on to 125 steel adapters....

VPA    

Most of my hunts are for Russian WB they are very though,but a WELL plced arrow with a SHARP VPA makes the job,no questions!  For my set up the 250 1-1/4" is the cure.you can't go wrong.

We hunted Ft STewart this past JAN and Feb.  Six pigs killed and all taken with three blade Broadheads.  4 VPA 2 G5 Montecs

In fairness, I think the guy that shot 21 hogs with the same 3 blade uses fairly high poundage bows, but it looks like a lot of hogs have been shot with 3 blades.  I have shot a few hogs with 3 blade heads, but I was using a 82# bow and had a complete pass through on all but one of those.  I haven't noticed  a much better blood trail with 3 blade compared to 2 for the hogs that I have shot, but I am sure that for all but the largest of hogs a 3 blade will do a fine job.  That being said, I wouldn't use anything that gave me a worse chance of getting an exit hole.  I would chose a sharp 3 blade over a dull 2 blade, but that isn't a necessary choice IMHO.

I'm with Pat, if two arrows hit in the same place, one with a shape two blade the other a sharp 3 blade and penetration is the same, so is the blood trail.  Last hog I killed a few weeks back was with a 200gr VPA. I've killed them with stingers, tuffheads, mangus I, mangus II, tiger sharks, stos, older woodsman and maybe a few other BH's I forgot about.  The only bad blood trails I've had were from my poor shooting.

All of my hogs were taken with multiple blade heads. Three blade elites or VPA and Four blade stingers. Some people I trust a lot said three were the way to go so that is what I did.

I am sure that your 3 blades will do the job for the hogs that you would encounter there.  I guess what I meant with my earlier post was that for me there is relatively little difference in the blood trail when there is only one hole, but there can be a huge difference when you get 2 holes. That being said, I wouldn't hesitate to hunt with either unless I thought I might run into a monster hog.  I know a guy that claims to have shot over 200 hogs and used to run a hog hunting operation who is a strong advocate of grizzly broadheads.  I know another guy who has shot over a hundred hogs, and he uses only 2 blades, although he has dabbled in 3 blades.  That guy has probably shot more monster hogs than anyone else has with a stickbow.

The only pig I have ever killed with my bows was shot with a 50 lb longbow a 550 grain arrow tipped with a wensel woodsman. The shaft buried up to the fletch and there was an incredible blood trail as the broadhead went straight through the top of the heart where all the arteries connect to the heart.

I have been experimenting with 3 blade VPAs and Woodsman Elites the last couple years and have shot multiple hogs and deer with them. To tell you the truth I am considering using them exclusively because I have never had a bad experience with them even with bad shots. I have had entry and exit holes in every animal. I shot one the other night with a 480 grain arrow to experiment and was very impressed!  I normally shoot 530-550 grain arrows though. Take care, Jeff

I shoot three blade Woodsmans for the most part, but any sharp broadhead in the right spot will do the job.

Use what you can sharpen best and what gives you the most confidence. Lots of great heads to pick from.    

Andrew ,Sounds like you fellas' are in for a good time! Use the broad heads you fell most confident in regards to getting it sharp and arrow groupings .
Good luck and shoot straight!
