Whisker Biscuit all the way!!,,so far i've been quite impressed with mine i have shot through it dozens and dozens of time with no wear to the biscuit or any fletchings, i put a very small bead of JB Weld on the end (front of fletching) just in case there was any tearing of my fletches going through any targets, and you know what i've done this for the past years and haven't really noticed any real changes in accuracy.
