As far as this discussion goes -
If someone is interested in shooting a fixed blade broadhead, I would recommend trying the Slick Trick Standards or the Viper Tricks. The Magnum is actually their original broadhead, and their Xbow broadhead seems almost identical to it. If there is a difference between the two, I can't tell what it is (except the Xbow has a 150 grain option). The Standard & Viper Trick (smaller profile) were added to the Slick Trick line up as time went on. Both are known for their accuracy & great penetration on animals like elk.
Trying different broadheads can be expensive. Testing different types of broadheads with friends would be the best situation, but we all don't have that. My local archery shop gave me a single used Slick Trick to test out at home. At the time (10 years ago), I had shot Muzzy broadheads for decades, & I hadn't even heard of Slick Trick. My best friend (he shot Thunderheads for decades) & I were both buying bows at the time, & we got the same recommendation. ST broadheads were also the dealers recommendation for turkeys.
Eventually, I decided to switch to ST. I chose the Viper Trick, because I was getting older. My current bow these past 10 years has been a 60 pound compound vs my 70 pound compounds of the past. I decided that I liked the design of the Viper Trick for my lower poundage, and they really fly nice on my spine aligned Victory shafts.
If your bolts don't fly well with either the Standards or Viper Tricks, I would stop there & explore mechanical broadhead options. Those who are shooting 450 fps crossbows & have tried fixed blades are ones you are seeking advice from. I totally get that! That's not a realm I have entered yet!
