I think that depends on skill, environment and genetics. I sure can't pull it off 6 zips all the time with autos. I'm more of the 3-5 ounce camp doing synthetic nutes and 1.5-3 so far with organic. I've done a lot of fast buds the last year and a half and I will say a lot of their genetics seem to be pretty big. I have not tried their ak-47 however. I think one of the drawbacks you might encounter with auto's is even the best bred strains you might not get that same consistency you would with clones.
