Had he said ARROWs rather than objects Jeff I would agree with you.
Again, what if he said bowling ball vs golf ball instead of OBJECT.
Rob....What in the world do you think he was talking about? Let's be real. It was article touting heavier ARROWS over lighter ARROWS.
I guess he could have been talking about sprinting cows v. sprinting squirrels, too. But, since the entire article centered around ARROWS.....I just assumed.
