@nicole2 Can you better describe your "mission" for your BC system? It all factors into making the best choices for your situation.
You've mentioned travel and your size, but that is about it for real inputs. How about for starters ...
Dive environment: warm and blue only? cold and dark? ....
Exposure Protection: wetsuit thickness range? drysuit?
Future goals: deep? wreck? tech?
Cylinders: single cylinder only? backmount-doubles? sidemount?
