Hi Eduardo,
I'll just share my own perspective, looking back over a few years of diving... and a good deal of it beyond the non-tech recreational realm. I believe the two courses that will add the most to a diver's competence, confidence and most enhance diving's enjoyment as a recreational non-tech diver are rescue and cavern. Rescue teaches you how to recognize developing problems far enough in advance to prevent them in the first place; cavern teaches you how to really hone your fine control of your body under water, and allows you to safely handle some really easy to get into but really hard to get out of situations that can easily sneak up on the average open water diver. Together they make a truly accomplished, relaxed recreational diver who can enjoy diving an order of magnitude above how much they enjoyed it before. I know it's hard to believe that there can be that much more enjoyment to an activity that seems the perfect joy already, but I think others who've got the hindsight of many years' diving will agree with me.
Bottom line, I recommend you take the rescue course and then the cavern course... rescue at around the 50-75 dive mark, and cavern at around 100 dives.
Happy diving,
Rick
