It sounds on the face of it that grommets is the way forward. It should cure the pressure issues that you have and give the chronic otitis a chance to clear up. You also get to keep your job!
Choppers obviously do climb and descend but usually not to the height that FW a/c do. Given that most a/c are pressurised to 8000 feet, as long as you do not go that high in your RW a/c then you should in theory get fewer problems with pressure changes. As they are not usually aircondiitoned, you also get fewer problems due to the drying effect, both of the aircon itself and the fact that high altitude air (whether pressurised or not) is very dry.
