I have had an Excalibur Equinox for 10 years or so. Always shot fixed blade Thunderheads or Slicktricks. Bought a tenpoint a few years ago and the Excalibur is a back up now. I got a killer deal on rage extreme's and they work well out of the tenpoint. I tried one out of the equinox (225# draw) and I missed the target at 20 yards. The rage opened and hit the sturip of the bow. Is it worth getting the red shock collars? they are made for 380fps and the equinox is around 320. As for now I will just shoot fixed blades out of it.
