I don't worry about anyone "pushing the limit". It's simply the result of a competitve market in a free society. The U.S. is great in this way. It gives people the incentive to think of new and innovative ways of doing things. If it works, then there will be a percentage of hunters who will buy it. If there's a problem then the company will go the way of the dinosaur. I don't know why it would bother anyone if someone else uses it. It's only obvious advantage is size. Everything else would limit the archers ability to take animals, from what I can see.
