RE: 3D range..
I do alot of 3-D in the desert. The wind always seems to be blowing(sometimes feels like a convection oven) the wind has a big effect on arrows, especially the light 3-D arrows. When the wind picks up. I go to a heavy set up on my other bow. The heavier arrows seem to have less impact from the wind.
I shot yesterday in a strong wind. One might think that I was handicapped with hunting gear shooting a 416 grain arrow. However in the wind, the other guys in the mens open were shooting the light gear, and their arrows were blowing all over the place. I ended up in 2nd shooting my heavy set up.
