So I was reading a thread started by berettashotgun and he mentioned ZZ birds. A few years back a friend of mine was in Italy and told me about ZZ birds and how it is popular in Europe, but I never gave it much thought. After reading berettashotguns thread it motivated me to do a little research on them. Man I want to try ZZ birds! Have any of you guys tried them and if so, how did you like it? It doesn't seem like there are any places in PA that has them, so I have a few questions about the equipment. Are the "propellers" reusable? Are they metal or plastic of some sort? Are the things in the center of the propellers clay or are they reusable as well? Also, has anyone ever seen one of the throwers for sale? I spent some time on google looking for the equipment for sale and came up with nothing. Any help is much appreciated! Thanks!
