can you use barrel swivels or does it have to be crane ? what size split rings do you use ? what is the size of your best performing spinner blade ? do you prefer willow, indiana or colorado blade ? I am pouring 1/4oz heads and current am using sz12 crane swivels, have heard of modifying the mold so that you can use a sz10 crane but not sure how to do it. My mold says to use sz12
thanks
