My department made the decision several years ago after myself and a buddy of mine proved to our administration that a smooth bore nozzle has itsa palce on the apparatus. We carry both smooth bore and automatic nozzles so that peole have a choice. I tend to disagree with some replies on the foam applications. It might dpend on the foam that you are using. We use F-500 and the manufacturer likes the smooth bore for its application as well as the fog. You proved with the TFT nozzles that we carry that we were not getting the flow the nozzle said or was designed to flow. We have seen better and quicker knockdowns with the smooth bore.
You can also hydraulic ventilate with the smooth bore if you only open it half way. We have proven this in training and real incidents. We are using the Akron 1 inch smooth bore on our 1 3/4 lines and on the hotel/high rise pack on my engine. We still have some convincing to do getting the smooth bores on the hotel/high rise packs. Some things do take time.
