Probably the most useful certiification for a new diver is Peak Performance Bouyancy. I found it best to do a few dives after Open Water to correct problems before they became habits. Take the two dive course and make sure you have time for a detailed debrief after the dives.
There is one session soon, but it is done with a drysuit and, to be honest, I am not keen to add the dry suit complexity into the mix. I had some problem during one of my dives because of the dry (I barely knew what I was doing to be honest). I will, however, ask around for a pool session.
Thanks for the advice.
