I have used the Sulky and it was fine. However, from what I have read, the 505 has less odor. The one thing I don't like abut spray basting is the odor from the spray. It goes away, of course, but while spraying it's best to be outdoors or in a well-ventilated room.
I have used several different types of spray. All worked fine, but all needed good ventilation while spraying.
