I have two theories on that fact. The first would be that anybody who really recommends a jacket BC is dog piled mercelessly so others who feel the same tend to keep it to themselves.
I've already postulated the second;
Could be that most SB jacket divers have their BC issue handled and have no reason or desire to visit this forum.
I believe there is a third reason:
people who frequent a forum like this are either very committed to their hobby, or very gear focused, or both. As such, they are more likely to give a "new" concept like BP/W a try, especially if it has it's origin in something "cool" such as tech diving. (note: I am making fun of myself as much as of anybody else who feels addressed :cool2: )
This might explain why at the Scubaboard appear to be more than the average 1% BP/W users (as we could read in another post, that's the rough market share of BP/W!)
Now, on top of that one can often observe that many people have the tendency to strongly advocate, up to being a missionary, their own buying decisions especially when they are the result of a long thought & search process.
And, of course, giving well intended advice is what internet forums are much about, isn't it?
So this might explain the large number of BP/W threads, while BCD users more likely just bought something in their LDS without much fretting. Which is, as we know, not so easy with a BP/W for lack of availability.
I, for my part, would not disagree that I fall in above categories. However, I definitely want to share my own experiences for what they are worth, and try to explain my "path" so others might benefit from the time and money I wasted on the way. After all, without such advice I would still dive my old heavy Shute and think there is not better way.
Btw, I have decided for a specific BP/W setup in 2005 and have not changed one single piece of it since then, other than repair. Pretty good, huh
Safe diving, d.s.f.
