Seems everyone has their own oppion on this topic. I like the exspandables , because of the way they fly and the blades help slow the arrow as it enters. Some use Thunderheads but the use of a small washer between the head and the shaft is a good idea to slow the arrow down aswell. Most pass thorugh shot require a turkey chase, keeping the arrow with the bird helps a great deal. Hope this helps you with your question...BT
