No question about it, Light Action model is considered by many as the entry level, non performance cleat arrangement. When fitting, we always recommend Zero pedals for the adjustability. Not sure if it is an "upsell" feature/benefits thing, but it is how our shop treats the models.
Personally, I dislike the cleat design of Speedplay and after experiencing clogged cleats from changing a flat on the side of the road, I no longer use them.
