Light arrow not tuned properly vs heavy arrow not tuned properly.... Neither will perform as intended, but which has the better chance of achieving adequate penetration to make a kill? The heavier arrow, of course. IMO, anything that gives the weekend warrior bowhunter a better chance of making a kill vs wounding and losing an animal, and decreasing bowhunting's overall wound/loss ratio, is a good thing. That is why I push the idea of establishing a minimum legal arrow weight of 400 grains. And I admit that is a solid 50 grains lighter than I'd like to see.

I was going to mention your product and my suspicion about your motives on pushing light arrow setups so hard, but I scanned the sponsors list and noticed you aren't on it.
