I shoot 3-d all the time myself, but I'm out there with my hunting setup - 650 gr arrows, 32" arrows out of a 29" draw, 5" helical feathers, great big fat pins, rubber things hangin everywhere and without a peep. The guys I go with do not just stand at the stake and shoot when ready. We make up shots, limit the time we take to shoot and challenge ourselves in ways the course doesn't. We've even entered a few tournaments doing the same thing. Didn't win anything but had a great time doing it. We also gain all the confidence we need when taking these same setups after game.
Well, that's what 3D USED to be all about, back when it started. It began as a game to play with our hunting stuff. No offense to those of you who shoot the class, but I still curse the day they opened the door to open class equipment and the game became full-fledged target competition.
