I agree with TSandM.
If you want to dive deep wrecks, make sure that your instructors teach you real gas management. For instance, you should be able to know the following:
-what gas to use and why (air or Nitrox, and what Nitrox mix)
-how much gas you need for the dive plan
-how much gas you need for emergencies
-when to turn around and head back (not just "be back on the boat with 700 psi")
-when you should arrive at the mooring line
-when should you use "thirds" and when you shouldn't use "thirds"
-what is the difference between open-water "thirds" and overhead "thirds"
If you read about all of the accidents on the Florida wrecks, it seems that most of them were precipitated by people either getting really low on air or running out of air entirely. These people obviously had very poor gas planning.
Start right now by meticulously recording you gas consumption, dive time and average depth, and calculating your SAC for each dive. You will need a good approximation of your SAC for future dive planning.
