first off im sorry to hear your story about losing your buck of a lifetime, one tip i can give you to get your muzzys and any other fixed blade broadheads to fly is PAPER TUNE YOUR BOW!!!, it is not a hard or long process and if you are not sure how to do it take your bow to your local proshop and they can help you out in extensive studies that we did with 5 different bows and arrow setups the single difference between broadheads flying like field points or not flying like field points was simply an out of tune bow.
