I' d like to know the tests showing the amount of energy needed to open a mech head. Of course it would be different for different heads, but all this talk about NEEDING a " LOT" of energy has me thinking...and questioning.
I guess we need to shoot a few fixed blades through some leather (as a comparison) and shoot some mech heads through leather. Have a chronograph on the OTHER side of the leather and measure speed (and with a little math...the resulting KE) the arrows have after going through (opening up) the leather.
PERSONALLY, I kinda like mech heads....but the group I hunt with doesn' t beleive in them...so I shoot fixed. When in Rome.....[8D]
