Here is a thought...don’t take anything for a while. Go dive! I am SSI. SSI requires 24 dives before allowing a diver to take "Advanced". You probably started diving because you love it - not because you can take an endless list of classes. If you must take something - go Nitrox or something skill oriented. Experience is the best teacher. There is nothing wrong with not being in a hurry to dive night or greated than 60’. When I first started my limit was 75’. Now I kind of look back at that and chuckle. I would rather dive with you as Open Water with 30 good dives than an AOW with 7.
