I just picked up a Fuego CT myself and I was going to set it like I've always set my Ambassadeur 500R (early low-profile, 5.3:1, mag system)
Tie your lure on, press the release, hold the rod out, loosen the tension knob until the lure slowly drops on it's own, one click tighter on the tension. Set the Mag level to '3', cast. If there seems to be some backlash attempt, turn the mag level up (4-5-6) until that stops. If the lure seems to be held back during the cast, turn the mag level down (2-1-0).
