Hi Bill,
Welcome to Rebreatherworld.com!
As what I saw from the Pictures, Tek Week on Grand Cayman looks like it was lots of fun.
You sure have found the right place on the www for info about all the RBs.
Look around in the forums, and whatever you don't find, don't hesitate to ask. Plenty of great and well experienced Rebreather folks are here to help and answer questions.
Again, Welcome on Board!
cheers,
RBN
