I made this exact recipe, as it was the one the brewer gave in BYO. Just kegged it on the weekend, and it's REALLY light. The 3oz. of c120 seemed to do nothing, but it's been a while since I've had Ranger, and can't remember the color.
It's all Grapefruit right now, so hopefully that will mellow out. The sugar really dried it out down to 1.009 from 1.060.
