actually, bigger antlers make a much different sound than small ones...
my thinking is that deer can tell the difference in that sound and know whether its 2 bruisers going at it or 2 scrubs going at it...
but, ive seen results from a tiny set of 1.5yo antlers that i use...and a NICE set off a pretty good buck for our area my buddy uses..his are big, heavy mass, and bladed..they had an awesome sound...
i NEED a nice set off a 1.5 or 2.5yo buck that has tines on it....lol..mine are real busted up...i actually have to work at it to get them to make noise lol...but ive rattled in deer with them...and i do like them coz they are small...
