I've used strictly raw prawns for maybe the last 15 years. They cast better, little fish cannot strip them and steelead and salmon hammer them. With corkies and such I use a piece about the same size as the lure. With Spin N Glows I use a wiggly strip of prawn. fifty cents worth of prawns will last me two days. Also they can be re-frozen over and over. No more messy eggs or soft sand shrimp for me.
