as far as size of the rattlin horn's go it dosen't matter I use a
rattlin bag a lot easier to carry as far as how hard to rattle
pre rut just light clicking together as the rut come's on then you can get into more of the hitting them together and louder clicking even break a few stick's as your doing this make it sound like a fight and add a grunt's I have taken alot of nice buck's doing this
good luck to ya
