im writing for huntinglife.com and writing a artical about what the most important part of bowhunting is to shoot accurately. VOTE NOW!

You forgot the main part of bow hunting... PRACTICE, PRACTICE, PRACTICE. Al the others are indeed important, but Practice is at the very top of the chart.

Arrows properly splined, sharp broadheads, and practice. You must be comfortable with your equipment and practice regularly and be proficient to make a clean kill.

practice in conditions you plan on hunting in.....
sittin in a stand? you should be sittin the same way when practicing.....
gonna have on camo? practice with your camo on?...
shootin broad heads? practice with broad heads...
wanna leave your wrist strap loose, always practice with it loose..( this one got me 1 time lol was too hot so i loosened it and sure enough drop time showed up haha couldnt reach the trigger)
practice holdin that bow at full draw fer 2-5 minutes and then shoot...
usually the deer wont stick around when you ask em to wait a second while you draw your bow.

I went for stance, breathing, and then I would add practice. The finest equipment in the world won't help you if you can't replicate the techniques from practice sessions. Anchor point up in the treestand is something that alot of guys don't practice enough.

broadheads, not that you need a specific kind but you need to maintain them. release, so you can hold your draw comfortably. and finally, scetn control/sit still, you need your game with in 30 yards usually

Before you get to the wood's practice, practice and practice. Then once you hit the wood's sharp broadheads and shot placement and I should mention that once your positioned in your stand Put Your Safety Harness On! Then enjoy the experiance kill or not.

Practice, shot location, and location of hunt ,being at the right place at the right time

You might want to check your grammar if you are a writer and going to write an article.

IMO, Form is most important! Proper stance proper release and number one is GOOD shot placement! If you neglect the above nothing eles matters!
