I've been spending more time practicing my form rather than shooting for accuracy since I got an archery net. The net is pure white and your arrow flight really stands out against it, flaws in flight seem to be magnified. I found I can shoot longer and concentrate better when shooting for form rather than shooting at a target. With the target, when I get a bad arrow I tend to dwell on it and things just go from bad to worse. When I shoot for form, I go all Keith Carradine/Kung Fu Zen Master. I get a groove going, feel a rhythm, and I start seeing just a nock with fletching spinning around it. With the large net backstop I can even relax to the point that I can draw, nock, shoot, and repeat with my eyes closed. I know it sounds HoodooVoodoo/Fung Shui/Airy-Fairy, but it helps you focus on muscle memory. It's muscle memory that takes over when your mind spins out of control over the t'irty point buck and you want to make that pure release that sends the shaft home.
I'm shooting about a dozen shots for form for every shot at a target and surprise, surprise surprise, I am now shooting more accurately. I just got some steel blunts to replace the field points that occasionally blow thru the netting so the net should last indefinitely.
I found that I can bare shaft test much more effectively with the white background of the netting, too. The 10' x 10' net is good for beginners because there is so much backstop to grab the arrow they lose/break far fewer arrows.
Has it made me the Second Coming of Howard Hill? H*** no! At least I don't suck so bad that I quit practicing because it just depresses me. I spend very little time behind the 3D looking for arrows nowadays and that says a lot to me. Let's home it leads to more practice following blood trails.
