I like wensel woodsmans, they are not quite as big as snuffers but they penetrate as good as any two blade in my opinion. Plus they leave a hole(smaller than a snuffer but still a wound that does not plug or seal like a slit.
Getting a passthrough is important with bear, but it doesnt mean youll find blood, sometimes they bleed internal. That said a double lung or heart shot and they dont go far. One lung or lung and liver and you can have a serious tracking job. I cant say it enough but really study the location of there vitals, I was hunting last spring and the camp I was at had 8 wounded bears for 20+ hunters. Most were actually gun but it made me sick, just not hitting the vitals. An inch off with a bear is the diffrence between seeing him fall from your stand or tracking for hours.
I shot a selfbow , plain jane , at fifty pounds and have got complete pass throughs through bear with woodsmans, heavy arrow is probably more important.
They are extremely easy to get scary sharp and fly like darts too.
