reddogge, I do a lot of shooting at pigeons as they fly out of my barn. Blunts without flu-flus. (lots of open field around me.) I cannot imagine shooting moving targets using 3-under. Of course I did not grow up shooting that way to begin with. I guess a guy can get used to any system if he sets his mind to it.
I have no doubt 3-under is superior at static target shooting. Most 3D winners are now using it. I find competition really does wring-out the best form for pure accuracy. Hard to argue with a man who is beating you shooting 3-under.
That said, it ain't for me. I'm too old and set in my way. Besides, I like the traditional split finger with my traditional Hill longbows. (and hybrids lol)
