Hi Ray,
I am going bear hunting in Manitoba this spring. Very excited about that, because I love hunting bear especially with Ryan Derlago.
I was considering using that three blade as well, but Stos two blades have always worked well on bear so far. I was wondering how much horsepower you need to reliably push three blade broadheads through critters. On the two previous bear I used a 53 lb and a 48 lb recurve bow with Stos tipped Surewood shafts for around 500+ grains. I had complete pass through with both of them.
