Thanks everyone for the very helpful information. Surprisingly, this is the first time I even heard of a BP/W setup. I had to do some research to understand what it really was. Definitely seems like a good option for travel. My only concern about this as a primary as well, is that i was confused about getting a travel bc to double as primary as well primarily bc i thought it would be good to have 1 bc that i could attach all my equipment to and leave in place so i can pick up and go.
Since i'm starting to accumulate alot more equipment like knife, lights, compass, safety equipment (mask, whistle, sausage) guide reel, and camera stuff, etc. i thought it may be good to have a bc with enough d-rings, pockets, etc. to keep all my equipment on so i dont always have to take it on an off.
With the BP/W and travel bcs this doesnt look as efficient as a full bc. Im mot concerned about needed to take my bc in a carry-on. I wld still check it. But just considering overall weight and bulkiness
It also seems that its a popular opinion that rear-flate bc's are more popular. So maybe i'll consider those. Even some recommend i3 system which seems pretty cool too. I'm advanced diver so i already know proper techniques for using a regular hose inflate bc. So 'cheating' that knowledge isnt a concern of mine. But it does look interesting.
I also dont want to pay $700+ for a bc. Looking to get a somewhat newer model in the under $500 range if possible. Would even consider buying used or demo model on a typically more expensive model.
I appreciate all your help
