Actually it's not nuts doegirl, the heavier arrow will actually perform better than the lighter one on a low powered set up. This is exactly where you would want to be shooting a heavier arrow, not a lighter one. Yes you will lose trajectory, but it can be compensated for. That is where the SKILL part of archery comes in. If you play enough with low powered set ups using light and heavy arrows you will see the heavy arrow has more energy, momentum and penetration at hunting distances. It's not an opinion, it's a fact.
You can argue it all you like and feel however you want to about it. However the people with more experience simply aren't going to buy it because they know better. Light arrows are not new, they have been around for quite a while. The reason they were not popular is because the bows of the time simply didn't have the power to make them useful. People tried them and found out the performance on game was not as good as a heavier arrow, so they switched back. This is also why you have seen a trend in the past 5 years or so for carbon arrows to offer heavier models. Now if you have a normal draw length with the capability to pull 60 or 70 lbs of draw weight the bows produce enough energy and velocity that you could use just about any arrow you want if you make a good shot. That being said I wouldn't suggest it for a youth hunter, or a smaller archer that can't get that much power out of a set up. Even if you are shooting a fancy bowtech.

There is simply no need for ultra heavy arrows, even with my setup or less powerful ones. All this ho-ha over arrow weight ignores more important aspects, IMO, like proper broadhead selection and the ability to tune your bow. In fact, I'll argue till the cows come home that poor choices in broadheads will lose you more game than light arrows ever will. I laugh when people suggest to me I should use a 400-500grain arrow.When the time comes I need to use 3 pins just to get out to 25 yds,that will be the moment I buy a recurve. Then I'll actually have a real reason to use such heavy projectiles.
