Right now I shoot with .029. Eventually, I'll switch to .019 so I can see the target better when I'm shooting past 30 yds. As it is, .029 is just too big for accurate 3D shooting. I can't go to .010, because I can't see the bitsy things! Not only are my .029 pins to big for farther targets, they also have an enourmous halo when I have to use my light. Yikes! That makes hitting the 11 ring even harder. I usually wind up hitting an 8. Sometimes I'll get lucky and hit the 10.
