Tying big pike flies uses allot of material for creating the large bulky silhouette. This also means more material to hold the the hook. All of my heads are coated on the angles cut-off end with superglue. The glue will wick up in to the ends of the materials for about 1/2 inch. Once dry, the deer hair and other materials will break off before they can be pulled out. All heads receive a coat of epoxy over the superglue, once eyes are applied.
