I agree withy Rob. Each shot is different and getting more oomph out of the bow won't be a guarantee of passthru's. There are just too many variables to each situation. rybohunter mentioned a few.

I don't quite understand why you don't get them anyway. 50# of energy should be plenty for deer sized game. Is it possible that you don't have the best of arrow flight? If the arrow is not flying true then it can be hitting the animal partly sideways, thus not putting all that energy straight behind the broadhead. Just a thought.

For example, almost all my shots are complete passthru's with as little as 39# of energy, but my arrow flight is as perfect as I can muster. Of course I shoot a slightly narrower broadhead, too. I limit my shot selection and range to a max of 35 yards, but most all my shots are about 15-25 yards.

If you think you are in need of a new bow then by all means try some out. And if money is an issue then look for some good used ones. There are plenty of 1-3 years old bows that would be a nice upgrade in feel and performance, but at about half the cost of a new one. Go with your gut and not all the hype. The latest and greatest isn't always the greatest for you, or for many others that follow the hype.
