It's always good to throw an equipment question out there when in doubt, although I'd like to make a couple of observations. The general consensus among experienced bowhunters is virtually unchanged; shot placement, a reasonably well designed sharp broadhead, and the animal's "body attitude" have a great deal to do with the ultimate outcome of a shot in the field. Some current writings attempt to point guys in specific directions when it comes to things like broadhead design, however, those conclusions are based substantially upon wound channels created in dead animal carcasses which obviously have their limitations. Traditional bowhunting is, and I believe should remain, a relatively simple and creative sport, resisting over analysis of equipment which really should be personal choice - within realistic limits. "Data" can be an interesting read but should always be taken with a grain of salt as this is hardly a sure science. I believe more emphasis should be placed on developing overall hunting and shooting skills which lead to a greater sense of personal accomplishment and ultimate success in the field. Don't forget woodsmanship!! As far as arrow setup, I personally lean toward the opinions of bowhunters who have had consistant success hunting a wide variety of critters in "the real world". There are many different arrow-broadhead combos that have proven lethal on the deadliest of game, in fact, a lady friend of mine recently put a Cape Buffalo down after a short 70 yard sprint shooting the smallest of the Simmons Sharks. Shot placement was once again a key element. Remember, develop woodmanship and shooting skills first and you will have a real sense of accomplishment!
