Tammy, there is almost a subtext in your messages.....that you try to train them so well it almost does not matter whether they even do the OW cert dives or not. I actually am sort of OK with this, and view the OW dives as just the next opportunity for people to get their act together. The biggest thing about the OW dives might be that they are OW....no walls, maybe not a bottom very nearby, not good viz, strange animals swimming around...lots of things that are a head trip but not really a diving issue. But, you ultimately have to get your head together as well as your buoyancy...
