Right you are - Sorry, was just mis- expressing myself,
and didn't think twice ..
And a polo shirt would indeed not be a good symbol,
Was just rationalizing about any goodie or twist, (to foster bonding even more) or such..
(Maybe a folder or so about diving, or Cousteau or a shell in plexi, or ...)
Not that the DSA's would require that, quite the contrary !
As they will be more than enough, by themselves, I agree.
Sorry again, carried away ..
Apologies, but Best,
