I had the Mares Dragon BC. It worked great for me. I like how the inflate area on the back wraps around the tank some to keep it stable. It’s a comfortable BC. I recently purchased a TUSA back inflate that has a replaceable bladder. I like the idea of being able to fix the bladder myself if something punctures it. The back inflate design also gives me more elbow room. The Mares Dragon also looks pretty cool.
