We have been selling and installing wb's on bows for three years or more now and ive personally shot em with blazer vanes and other vanes. If your vanes are getting torn by the wb then your bow was not tuned for it. A wb slows most bows dwn bout 5fps on average. I put one on my new bowtech marquis and i didnt see any change in performance over the drop away i was using. So unless you are a serious target shooter the wb is the best way to go for hunting in my opinion for what thats worth
once you shoot a bowtech you will never be the same.
