Rage broad heads are good for one or two of these types of threads every year. Used them, don't use them any more but I will say this:
A double lung shot is only verified on recovery of the deer. You can speculate all you want about what you saw at POI but my experience is on double lung shots, you find the deer within 60-70 yards almost always. In fact I would rather recover deer that are shot through both lungs than the heart as it makes my job so much easier as double lungs fall within sight or crash within hearing distance.
