Gee, DevonDiver, that didn't take long. Bravo! The ad hominem fallacy - attack the poster, not the idea. Please read the ToS.
How was mentioning that you had 50 dives experience "
an attack"?!?
It indicates that your theory is based upon a very small breadth of experience - which can be used to explain why you fail to understand some of the wider issues that are considered in the debate.
Please read my posts - I did not suggest, ever, that a BP&W is unsuitable for a given dive.
Your post indicated that some BP&W advocates were somehow
incorrect to recommend that equipment on the basis that they didn't understand (or had failed to ascertain) the specific needs of individual divers.
Myself, and others, have responded by questioning what specific needs divers could have, that would make a BP&W unsuitable.
Myself, and others, have responded on the basis of experience that has allowed us to dive with thousands of other divers, in numerous locations, doing numerous different activities. Do you really think that we 'fail' to ascertain the divers' needs? Or could you believe that divers with hundreds, or thousands, of dives experience...as buddies, mentors and instructors.... might
have learnt exactly what these divers needs are (and, hence, do not have to ask)...
I merely suggest that a BC (such as a Zeagle Scout) might be just as suitable for a tropical drift dive.
I see no such suggestion in your post.
What you may fail to appreciate is that recommendations/comparisons for BP&W extend far beyond any single specific diving circumstance. Those, experienced, divers who recommend BP&W do so on the basis of their breadth of knowledge about how divers' requirements change, adapt and progress over time.
Given your relative experience, this is a long-term concept that you won't have any first-hand experience of. However, it is something that instructors and highly experienced divers will have encountered over their personal dive histories...and through first-hand contact as trainer and mentors for other divers.
So...yes... a Zeagle Scout
may be on a par with a BP&W for a specific tropical diving scenario. But it won't 'grow' with the diver over time. It won't adapt to the divers' needs in other locations. It won't help them transition into tech. It won't enable flexibility through a modular construction. It won't form the basis of a 'balanced rig' for their buoyancy needs.... etc etc etc.
