Westcoastsaucey,
I’ll echo the recommendation that you first determine what type of diving interests you most.
Perhaps a better way to provide you an answer is by asking you a question first. What are your current outdoor hobbies and how do you approach them? That may help reveal some aspects of your “personality” and help us to guide you.
If you envision yourself mainly hitting the dive resorts and following along, then perhaps a jacket style BCD is just fine.
If you’re already a bit of an outdoor explorer and your aspirations are varied, then I’d recommend pursuing a backplate and wing because of its modularity.
I started out with a back inflated horseshoe wing on a soft plate. While I liked it, I often had to change pitch to move the air around in my bladder to achieve the trim I wanted. When I switched to a SS backplate and a donut wing, I got rid of my weights, my trim settled and I flattened out immediately. Your air balances out much better in a donut wing. Because I no longer had to squirm around trying to adjust the air in my wing, my consumption also improved significantly and I started extending my dive time to 90 minutes or longer.
An Australian dive buddy in the air transportation business has been diving around the world since 1986 (so 33 years). He recently purchased a BP/W and was positively surprised in the instant change in his diving experience. He felt a bit sheepish he had dived for so long with a jacket style BCD.
With a backplate and wing configuration, I like that I can switch from a single tank wing to a double tank wing in matter of minutes. I also like that I can travel with both wings giving me the flexibility to dive the way I want. 12m single tank dive with my wife and daughter? Cool. 50m twinset dive with buddies on a wall looking for some big boys down deep? Also cool.
The “excessive weight for travel” claims about SS backplates are exaggerated, IMO. I’ve travelled with mine between Florida, Europe and the Middle East and I have yet to suffer under the long arm of oppression by an airline or induce a back injury.
Consistent with what Eric shared above, know that many of us have purchased some kit with the best of intentions only to find out later that we need or simply would like something else. SCUBA diving is not a cheap sport so probably best to accept that you will have to undergo some trial and error.
Good luck and enjoy the journey.
