I don't think it matters realy, my brother was hammering in a tree step a few years ago and had a buck come busting threw the woods right to him to see what was going on. My friend and I use the rattling bags. He rattled in a big buck and a couple small ones one night, then the next night I arrowed the big one that he had rattled in. It was 144" 10pt. I just find it easier to carry the bag because I carry a climber also. Just my thoughts.
