I dove a TUSA BCJ-4900 Imprex Pro for about 300 dives. I liked it ok at at the time as there were few back inflate B.C.'s around short of a back plate and wings on one extreme and something with way too much crap hanging of it at the other. It had a pair of cam bands which were secure and stable in the water but it was a bear to rig my 30 cu ft pony and doubles were not an option.
A few years ago I threw it in the closet and went with a Genesis Recon. I added the optional stainless steel backplate and have been quite happy with it. The pocket is more functional and the D rings are better positioned on the recon. The weights are positioned much better, do not ride on your back and the weight release system is much better designed and the handles do not come loose to flop in the current. The dump valve on the bottom of the wing is also easier to find and the construction is heavier overall than it was on the TUSA.
It's a good BC and works quite well with my standard configuration including doubles, a lift bag and when required, an OMS Phantom dive light and/or an argon bottle attached to the backplate.
The bolts on the waist and shoulder straps are enough to drive a God fearing Hogarthian diver over the edge when they see it, but I've never had one come loose in about 250 dives with it and I like the easy adjustability when switching between drysuit and semi-dry.
I dove it without the backplate for a bit and I have to say I really recommend the backplate. It makes it much more stable underwater and much more functional for any type of technical diving. On the downside, by the time you buy the BC and chuck up another couple hundred for the badly over priced plate kit with the "you get it whether you want it or not" single tank adapter, you have over $600 invested and could buy almost any other plate, wing, and harness system for the same or less money. Genesis also sells a redundant bladder for it for another $270, but this just aggravates the sticker shock. I like to support my local dealer, but I have limits.
