Thanks for the input! Sounds like I'm ok where I'm at.

For what it's worth, Winke was saying that range is a good compromise between speed, penetration and noise. Here's his exact comment:

Lightweight arrows produce a flatter trajectory, making distance estimation not quite as critical. Onthe downside, they absorb less of the bow's energy (so they don't penetrate as well) and they make the bow noisier. The best compromise between speed, penetration and noise is an arrow that weighs between 6.5 and 7 grains per pound of maximum draw weight. In other words, if you shoot a 60-pound bow, your finished arrow, complete with broadhead, should weigh between 390 and 420 grains.
