As far as the "techie" side of things, I cannot see any link between that and the level of hunting competence.

For example, some guys just drive their vehicles, others insist on knowing about and tinkering with the systems within. The point is that some people are simply more inclined to learn about the dynamics of the bow (and arrow, etc) itself. Naturally they tend to be more "hands on." How can that be linked to hunting skill?

If you tune your equipment, and I have a highly competent pro-shop tune mine, do we not wind up with two tuned bows? What happens in the woods thereafter is an unrelated matter.

Great topic, silentassassin.
