i prefer pass through...just for the major reason you stated. blood loss. not only does t make a nice trail....you know where you hit the animal. that whole deal where the broadhead bounces around cutting just isnt the case many times. if you dont get pass through often its because a bone interfered. in which case, the broadhead is lodged in the bone and it stays stationary cutting only connective tissues. ive seen a broadhead lodged in the scapula, and the arrow actually unscrewed from the broadhead as it bent and when he ran it was like a crank getting uncranked. it was my deer. i shot that same buck the following year. my broadhead was still in there lodged in the scapula with a mass of hard flesh having grown around it.
pass through shots are pretty close to sure things unless they are through the guts....then often you dont get your deer but it dies anyhow. non passthrough shots are often wounding shots as well....because more often than not there was ome interfereance.
that being said...with a perfect shot there is no reason an arrow shot from a 35# draw wont go through a deer if hit properly.
