Just wondering if you have heard of anyone using NAP Spitfire Doublecross having trouble with it shooting heavier than other mechanical broadbands. I'm shooting a Hoyt Defiant Turbo so I have the speed that I normally don't have a problem shooting heavier stuff. I can shoot the Doublecross and be low enough that I have to move my HHA up 5 yards but will shoot normal with my field tips or my Rage or Toxic.
