i think it somewhat depends on what type of deer you are after. i wouldn't think that a 100 class buck would come chargin' in to the sound of 2 130 class bucks going at it, whereas a 120 buck may be a little more intrigued at the sound of a pair of 100's bumpin antlers.

kind of like bass fishing, a 1 pound bass is less likely to hit a 7 inch topwater bait, but a smaller bait is food for any size fish. just my thoughts.
