My instructor is suggesting the Diverite Transpac or transplate.
The main reason that those of us who dive and recommend a backplate/wing (BP/W) setup is the simplicity and streamlined nature of such a rig.
It's great to "try" lots of things before buying something. But more important is to really try to understand the differences between different things... and what the pros and cons are of different configurations are. Some of those things are counterintuitive.
Consider how much stuff is going on with the Hera. What you perceive as "all the personal size adjustments available" may be an illusory benefit for many people. Multiple extraneous buckles and clips and belts and velcro sound "adjustable" but the reallity is that all those things often conspire to ensure that it never really fits you properly or fits the same way twice. My personal experience with a recreational BCD (AquaLung Balance, which is great) was further compounded by the fact that the buckles and clips and straps always seemed to be in the exact wrong spot - sitting on a collarbone, poking a rib, etc.
The other challenge with something like the Hera, is that all that "stuff" is plastic/nylon/etc and tends to float. A typical recreational BCD is usually 4-6 pounds POSITIVELY buoyant. That means you're wearing 4-6lbs MORE weight simply to sink your BCD.
Compare that to something like the DiveRite TravelPac (which is another option, especially for someone smaller, as it comes in different sizes.) From a sizing perspective, once you have the rig set up right for you... you're pretty much done adjusting it. It's also not that buoyant, so there's not much "extra lead" penalty associated with diving one. And from a streamlining standpoint... the rig speaks for itself.
Lastly, I always suggest that divers consider/evaluate the purest form of BP/W rigs as long as they are in the market. Comprised of a single continuous piece of webbing, the counterintuitive thing is that the lack of buckles and straps actually INCREASES adjustability by allowing for infinite refinements that are not limited by the location of buckles/straps/velcro. As for buoyancy, the use of a metal backplate gives you a BCD that is NEGATIVE. So not only do you not need EXTRA lead to sink it, you can even reduce the amount of lead used. Lastly, the extra benefit of a metal plate is that it locates ~6lbs of weight spread out over the exact area where your lungs are located. This avoids the teeter-totter effect of having a torso that is positively buoyant and all your lead on a waist that is negatively buoyant.
Ultimately you need to buy what works best for you. But the issue is that diving is very much UNLIKE other sports. In something like skiing or cycling or camping, beginners tend to start simple and add the things they find they need as their skills and experience grow. In diving, there's a tendency for new participants to start with gear that has all kinds of superfluous features. Then - as their skill and experience expand - they SHED the unnecessary stuff and end up with a simplified rig.
