I have a set of 8pt horns that would have scored about 115. i think they are ideal. i used to have a smaller pair, lots of small bucks came in so i went to a big pair and the little ones shyed away, but still got responses in some cases from the lil' boys. i thinks it's more a matter of mood. i do know that rattling does not scare deer. if a deer is in eyesite just don't pound them together. you have to remember that if you can see the deer, likely he can pinpoint your rattling spot and if he doesn't see another deer, he certainly isn't gonna respond. if you are gonna rattle in open areas, i would use a deke. just my two cents.
good huntin' boys
