Was there any Halcyon weight systems back in 2000 or even earlier.

Take a look at the dates of the non-patent citations for the Active Control Ballast system: https://www.google.com/patents/US7458751#npl-citations
22nd and 28th Aug 2000 ie. not yet 15yrs.
I thought it was less than 10yr.
I give you that.
And 3Ddiver is surrounded by divers in BP/W and doubles. His gear works very well for him, so there is no need to spend money on a change.
Where we dive it seems most of the 'regulars' are in bp/w and the others in more traditional bcds. Or maybe it is just the company I keep (not 3 letter groups).

If I dive in a shop based trip through my LDS, there will be 2-3 BP/W kits. One Instructor, myself, and one guy (my buddy) whom I converted (maybe a 4th if the Instructor's wife makes the trip as a DM).... that leaves the other 30+ divers in jackets.
If I go out on a charter (usually filling seats available from out of town shops), there will be 1 or 2 conventional jackets and 15-20 BP/W rigs....
Shops here do not sell them.... why? I know not....
When I took some advanced certs here, the instructor was jubilant going over my rig with the other students. He was using a conventional jacket for the dives, but did break out his BP/W for the last dive(s).
Again, if the staff even likes them , why do they not sell them?

As this thread is alot about what is important about a bp/wing system...what are the key points...how should weight be used in one, etc....This DIR 3 video is relevant and free 
George Irvine is absolutely NOT obnoxious in this, and in many instances quotes from the PADI manual, and refers to it as a place to find great common sense ideas--very much so over the manuals of some of the tech diving agencies in the late 90's ( this was shot October 1999).
I am in the middle between Bill Mee on the left, and George on the Right ( for those that would ask ).

If you want to avoid the intro, at 10 minutes in George begins his explanation about what is MOST important in a bp/wing system...and while Halcyon is used in this, what he says could be ideal for the vast majority of bp/wing mfg's. But you may find the intro is worthwhile, as it gets to the heart of many of the bp/wing and general diving common sense that we are talking about here...
At about 50 minutes in, there is a demonstration of how to configure and "fit" your harness, that is worth a watch.
***Note.....When George shows how easy it is to pull the Harness and tank off--this is a demo mentioned because of a WKPP and tech diving need to be able to take a tank off easily "IN" the water. This becomes relevant in the discussions about how some divers think they need chest straps--George explains why with correct fit and config, you don't need a chest strap....and makes a case that the bp/wing system is created for ultimate comfort in the water when using it...and that "fit and comfort" when standing in a show room, is the wrong physics to worry about.
Just after 1 hour in, there is some amazing cave footage of Wakulla.
