Other than the basics, scent control, hunting the wind, stand entry, even using the sun location to your advantage the absolute biggest way to get an advantage is to Hunt!!
You can Not kill'em unless you are in the woods with your Bow!
I'll put my money on a Nimrod that can hunt everyday over a seasoned hunter that only gets to hunt a few select weekends. If you know the basics it boils down to time spent in the woods, location, and a measure of Luck.
I'd rather be lucky as good any day!!
