Sometimes, while what we have works, there comes along something that may work just a smidge better. Like the conversation you and I were having about the Viper Tricks. My Standard slick tricks have served me well for several years. But those Vipers just MIGHT be that little smidge better. Might fly just a touch better, may leave just that 1/8" bigger hole that may bisect a vein that the standards may have just missed. I personally like to stay in the loop with new broadhead technology and I like to use the absolute best broadhead that matches my style of shooting and my bows speeds.
