One thing I can tell you is that if you can't draw your bow back and keep it steady, I don't care if you are shooting Elk, you will not be as stealthy. Your better off shooting 60 or so pounds and driving nails at 40 than pulling 67 and not hitting very well at that range or even closer. And 60 pounds is plenty to take big animals like Elk at even 40-50 yards with the right broadhead. Shoot the poundage that is the most comfortable to you, and you shoot well.
