Well there are some variables. Some look at speed, some look at kinetic energy, some find a happy medium.Buckfu said:
But you always have to look at FOC and spine. There are charts that will help you. I can find the links if ya want.
For example with an 85 grain broadhead on a 29" goldtip 5575, and pulling 70 lbs, you will have X amount of speed, kinetic energy, and FOC. Go to 63 lbs and switch to a 125 gr head. Every thing changes. In reality, the common hunter probably doesn't worry too much about everything together and kills alot of deer.
In short you don't necessarily need to "tech out" to hunt well.
But alot of deer are missed or hit bad and/or not found, where
with a good arrow setup this might be avoided some.
Hope this helps
