JMHO but I would recomend the 2oz, big enough to minimize propellent leakage ( my understanding is that there is always some leakage from the valve assembly and that the larger units can last longer since proportionetly less is lost in the same time period.) I understand that it is recomended to replace them once a year regardless of size. I would not recomend the 4oz due to difficulty in carrying and concealing and a 2oz that you or your girlfriend has on you is much better than a 4 oz or 1lb unit left at home.
As far as stream or fog, beats the heck out of me.
