Nope, not yet. Haven't found the right match of condition & price.

I lost touch with a buddy of mine (also named Bob) who had a set he picked up new in '58. He was still diving them in the early '90's, he might still be diving them.
Just the oposit here. After trying a backplate I will nver again even consider diving in any bc especially a jacket.

Ditto that Mike!!
Ohh and can someone remind me what year this is? I'm getting confused with Bob and Walters talk of 72's and triple 40's.
This being the tech section and all...
If I have to do much deco rather than use triple 40's I use two 80's. As far as doubles I'll keep my 104's. I might double a set of 72's for a tech dive to 60 feet.
Where do you put reels or backup lights on a jacket?
ok so I'm opinionated.

Keeping in mind everyone is different and entitled to their opinion..........I prefer a SS back plate and wing to any other sys for doubles. They are secure, and I remove any weight from my waist through the addition of gear. As for useing tripples, or unusual configurations like that, the expense of binding them together, the addition of manifolds and running more hoses is unnecessary when a larger set of tanks will reduce cost, risk, and contribute to being more streamlined. Those of you who do doubles just for deep dives, that's great. I however use them for most boat dives, because I don't have to chase tanks, I feel more secure having the air as opposed to wanting more. My ballance is better with the doubles. I like having all the reels, lift bags, stages, etc., it's a nice to be able to manage all that stuff. I wouldn't be carrying it if it weren't for the harness and back plate. On the other hand........They can be heavy! I do alot of shore diving. There I prefer a 120 or 135 and an 80 for a pony. I have knee problems and don't want to carry all that stuff to the water at one time. Doubles are an excellant way to extend your BT in shallower water if you choose. They are a must for deeper diving as you have to consider enough gas for your partner in the event of trouble. In this country people buy things not so much out of need, but want. Get them if you want them.........JUST make sure you know how to USE them correctly, and safely. You don't strap them on and go...........If you have questions ask, or consult an accretted agency first!

Thank you everyone for your kind and informative answers to a novice. It sounds like there are four primary reasons for using doubles:
(1) Extra air for non-deco diving with nitrox @ 100/30m
(2) redundant tank for wreck diving (I assume this requires two regs as well?)
(3) balance (Bob are you referring to doubles being more balanced than diving a single with a pony bottle or are they just better balanced than singles in general?)
(4) Decompression diving
As I am a beginner (<25 dives) I wont be using doubles in the near future. I am not sure I will ever get into deco diving, as my time and wallet may not allow me to do it right & safely. But I will definitely dive at 100 with nitrox and as I am a big guy, even when I become more efficient I may still be a bit of an air hog so I may go with doubles at that time. Since using doubles for me sounds likely in the future I will avoind the Stab Jacket -> Ebay -> BP or Doubles Jacket pattern and get a BCD capable of using doubles now. I will probably end up with a backplate since people seem very happy with them even with single AL80s tropical diving and if I eat my words 5-10 years down the line, I will be able to switch to deco diving.
If the time comes that I want to switch to doubles for non-deco diving (for air consumption on nitrox at 100) is there a specific course/training agency anyone would recommend? And can you do wreck penetration in N.C. without deco diving?

There isn't a whole lot of penetration on a lot of the NC wrecks, but stuff like the Indra can be penetrated easily without racking up a deco obligation.
Like Wreck/Tec, I use my doubles for most of my dives. Given the choice of carrying the weight in the form of large tanks with tons of gas or as otherwise useless lead shot, I'd rather have the gas.
Besides, using the doubles on shallow dives is good practice for other stuff.
I still use my singles for some shore dives.
Going with the BP is probably a good idea. Its easy to switch from singles to doubles if you so desire. In the meantime, you will have a nice singles rig that, IMHO, is quite comfortable.
Good Luck
