I have a Guardian and I just traded my 70# Vectrix as these forums have taught me that 70# in a modern efficient compound bow is not necessary. My stats prove it: My 29" Guardian is peaked and registered 62# on the bow scale. My A/C/C hunting arrow setup with a 100 grain head weighs 394 grains. I averaged 273 fps through a $600 chrono at Buck Hollow Sports in Pella, IA.
