Hobbes, welcome to traditional. What everbody has said here is true so you can see that the mechanics of traditional shooting are varied greatly. Watch the videos and read the books but when it's all said and done the magic word is consistancy. I shot split finger for the first 25 yrs. of my bowhunting with good success but the last 15 or so I switched to 3 under for only one reason and that was shooting at walking game form a tree stand. If your ever going to miss a close shot using traditional equipment your going to miss high and it's not because of gravity being less or anything else it's because of the angle of your arrow being pointed at the game. With split finger you have to mentally hold well below at point at 10 yds. just to hit it. With 3 under the arrow is closer to the eye making that much less of an angle. From a tree stand shooting split finger that angle is magnified greatly by the angle of the bow arm. You have to really bend over at the waist to assure the same "sight picture" and arrow angle. When your under the pressure of shooting an animal some of this goes away and I found that I get more room for error by utilizing the 3 under. Just remember, don't settle for less arrows in the "kill" of a deer target than what you would with your compound. Your distance may shorten some but there's no reason for people to be poor shots just because they switched to traditional.
