Man I wish I would've read your comment before making my decision!? I chose Hunting, for Marksmen Fang. But instead I received Ballistic Shot. Confirming what you said about it being a pool rather than fixed as stated in this guide. In hindsight I should've reloaded a few times just to see what the possibilities are, but truthfully I was fine with Ballistic Shot & wasn't thinking about the opportunity to fix this guides accuracy? Hopefully your comment helps someone else.
