RE: Who said that physics wasn't fun?
You are heading down a slippery slope if your thinking is in that direction.
Under the set of circumstances the game comission must regulate the hunters arrow weight, how about draw weight? How many guys do you see doing the "sky draw" because they can't pull the bow straight back due to shooting too heavy of a poundage? Do we now require minimum AND MAXIMUM draw weight checks? How about the gun hunter that just takes is gun to the field thinking that "it was sighted in at the end of last season, it must still be on, does this require a yearly certification sticker on your gun that it has been sighted in properly? Possibly we should require the recurve and longbow shooters to prove they can hit where they aim before allowing them to the field with their bows.
I am not trying to get into a pi$$ing contest, but adding more equipment mandates leads to nothing more than more equipment mandates. The recurve guy that can't hit the broad side of a barn is still going to gut shoot every deer he sees regardless if he was shooting a soda straw or a telephone pole.
I understand what you are trying to accomplish with the heavier arrow weight, but that will come with education, not mandating more regulations.
