I have dove many different BC styles starting with the old horse collar. Currently I have a Beuchat "Tec" back inflate BC, its been a good BC. If I had it to do over I probably gone with the Zeagle (more places service vs Beuchat). I have also dove a Dive Rite BP&W, and it was fine. IMHO my BC was more comfortable. This sport can get pretty "tecy". You have to be honest about the type of diving you are going to do and how much. Are you really going to go "tec", dive duels? The vast majority of us are basic OW divers on 80 alums. Any of the top back inflate BCs will work great for you and your wife. My wife has an Scubapro Ladyhawk and loves it.
