can't agree that RA diving in currents always works like that. It's more like there is some current you will deal with on most if not all dives and it can increase/decrease/change direction during the dive. Until the moment you are in there, it can change. Since the current areas are where you find the action, that's where we tend to dive. Good guides will be able to adjust for that during the dive. The point is you should be reasonably comfortable in the water and dealing with your gear and making your safety stops. Beyond that, you should be reasonably fit to be able to handle kicking into it for some time so you can handle those usually short periods that you need to without over exertion.
