RE: Need tech help
Hmmm, you currently have 61.38 ft lbs in kinetic energy. Switching to 85gr broadheads might get you an extra 5-8 fps. So, you're looking at 61.45 ft lbs (maybe as much as 62.86 ft lbs). I'd say you're sweating the small stuff. What's more, you'll end up messing with your foc and retuning.
Concentrate on your shooting form and accuracy, especially from longer ranges (because this makes you better at closer hunting ranges). Accuracy is what kills deer, and you can never have enough.
