Honestly you really can't. Not when it comes to shooting bow and arrow or even rifles/handguns. It is way to variable. You would have to have the exact same arrow weight to the thousandths, the exact same broadhead weight to the thousandths, your shot would have to be exactly the same and your ballistics gel would have to be the exact same consistency which is impossible. This slide hammer won't just blow through a target assuming it is lightweight. I am willing to try it the main reason being I am a little low on kinetic energy. I don't want to go to a heavier set up so we will see assuming this thing is lightweight and hardly effects speed. I too would like the makers of this product to post more on their website, I did not know this was only out for 4 days. I think we outta be patient. Also Chaos I think you should let the makers of the product do their own marketing. Just be patient. I do appreciate you notifying us of the product though. Interesting.
