This is an interesting thread to me.
I too am new to diving and only have 1 dive (well 2 dives in one morning) after my OW certification. I've only used rental gear thus far and both have been jacket style. I too am like you
@bvbellomo that I am a sinker. During my OW/AOW dives I started with 14lbs. When we were doing AOW dives the instructor noticed I was putting way too much air in my BCD so I then tried 8lbs. Still he said it was too much so I tried 6lbs and it was PERFECT. Then on my 1 dive 2 weeks ago I used 6lbs again, and once again, it was perfect. I'm 200lbs too.
I'm in the market myself for my own gear now and pretty much EVERYONE has recommended not to get jacket style. I luckily found a LDS that has some back inflate BCD's that they are going to let me try out in a pool next weekend. One is the Hydros Pro and one is a BP/W setup, so it will be good, regardless of which direction I do end up going, to have some actual hands on experience with difference types other than jacket style.
I was VERY close to purchasing a Cressi Travelight myself but I won't be diving until either July or September again, so I'm in no rush and thankfully I held off the itch to just purchase something.
The main benefit I see of the back inflate ones is just less bulk. I definitely feel like there is a lot of bulk in front of me when diving thus far, but I have adjusted to it. I know another benefit people say is that when using BCD since it's on your back, it puts your horizontal versus vertical, but with how little I air I used in my BCD on my recent dives, I don't really know how much that will benefit me.
I'll be curious to hear what you do end up going with though.
