I am shooting 39# at 27.5". I shoot a 400 to 450 grain arrow, that includes a 160 to 200 grain broadhead. I only take shots broadside or quartering away. I hold out for broadside shots if at all possible. I like the 2 blade. I have never had problems with lack of blood on the ground with a proper broadside shot. On two occasions, with quartering away shots from a treestand, I recovered the deer, but there was not much blood. The broadhead did not exit the deer. Some say that the 3 blade is stronger up front for penetrating bone. I have hit ribs with my 2 blades and the broadheads were not damaged. I think the talk of broadheads penetrating bone (shoulder, shoulder blade) is unhelpful. I think that a ton of energy with a very heavy arrow would be necessary to go through a shoulder or shoulder blade and humanely kill a deer. I think that going through bone (other than a rib) is bad news as is trying to get set up to do so. I know there are people who disagree. Just my opinions.
