There have been lots of threads and debates on here about "why do you need a heavy bow", "Is such and such weight good enough for deer, etc..." and so on. I don't really care one way or another, shoot what you are comfortable with and be proficient with it is all that I ask...and of course legal for the game you're hunting. However, I do have a really good reason for owning a heavier bow. I recently got back from Africa and had a very successful trip. I took a 51@28 recurve and brought back five big game animals. I was fortunate that all of my shots were very good and every animal died quickly. I did notice however, that my bow, while adequate didn't leave much room for error as far as penetration was concerned and I told myself that when I return I will take a bow at least ten pounds heavier. Fast forward a couple weeks and I got a steal of a deal on a 61@27 Northern Mist American, which is probably 63-64 at my 28" DL. I haven't even shot it yet (waiting until hunting seasons are over to concentrate on that), but have been pulling it back a few dozen times per day. By doing this, it has made my 51 pound bows feel like toys. It allows me to hold rock solid and anchor much better and my accuracy has improved because of it. While it seems like heavy bows get a bad rap these days, I've come to believe that if you want to really shoot your bow well, get comfortable with pulling 5-10lbs heavier than what you're used to and you will see a definite improvement to your shooting. One last thought. Be smart about it, don't go out and try to horse back something you're not capable of pulling back. The reward wouldn't outweigh the injury, but if you try this, I believe you'll notice a positive difference in your shooting. Worked very well for me, just thought I'd share.
