It sounds like you may have been there during higher current or at least expectations of lower current in some spots. The currents last Nov and this Feb were slow to non-existent in some places for those days and weeks we were there. It changes constantly. I have found Yucab and Tormentos to have faster currents than other sites but I have also dived them when the current was mild but rare. It depends on the time of year, storms, wind, or which foot hit the floor first thing in the am.
I don't understand the description of Dalila and Paso de Cedral as flat and featureless. These are two of my favorites and for photography as well. Paso de Cedral at night I think is very good. The current on Paso de Cedral can be quicker but there are many places to duck behind. The group has to stick together though or you no time to poke around.
I found that the single most important factor in the varying strength of the current at different sites was the topography. The flatter sites tended to have stronger current because there were fewer coral and rock formations to break it up. The sites with the higher rock and coral formations tended to have the least current, perhaps because the rock and coral formations broke it up.
Paso del Cedral and Dalila had a lot of great subjects for photos, but the strength of the current made it hard to stay in place and often added motion blur.
