RE: Arrow penetration vs. weight
Agreed. Conducting tests are funand I'm personally not saying that you shouldn't do them with the equipment you have. A few months ago I did my own testjust comparing heavy VS light and ignoredarrow diameter. lighter thinner arrow out penetrated heavier thicker arrow in the media thatI used. It was a fun test andallowed me to shoot twice as many arrows that day.
The tests allow you to see the difference for yourself.So, please do not stop on our account.
