STAs and What size wing for BP?

[jasondbaker]

Some of the halcyon single tank wings have a STA built into them. I think it works very well.

I think the diverite venture is okay. You might want to look at oxycheck stuff. I hear good things. Do not buy a single tank wing over 40 lbs.

You don't need the pony (whole separate debate). Find a good dive buddy and stay within recreational limits.
