Three-blade broad heads were used to take several javelina during the hunt -- both snuffers and woodsman let the air out of the little buggers pretty well.
The long trailing jobs were more a function of the heavy cover than the lack of effective cutting.
The cover is something to behold. You week-2 guys will be wise to bring pruners and small saws as well as tweezers.
Crawling through the cover to follow blood is slow and difficult -- sometimes it can be belly crawling and/or hands and knees. It can be a very slow process.
A very bright flashlight can help you see the blood in the darkness of the cover.
If you have snake chaps you will have fewer thorns and spines embedded in your hide at the end of each day.
Last, listen to Terry. He has javelina knowhow.
