I started diving with the Scubapro Buoyancy Control Pack - a late 1970s design. This basically used the platci scubapro cam pack with an additional plastic plate that sandwiched a wing to the cam pack. A benefit of this approach is that it gave the wing a fairly wide base of support that reduced the tacoing effect when used with a single tank.
The Deep Sea Supply wing would work well in this regard as it uses a fairly stiff center section that accomplishes the same thing and has a similar lift capacity to the old Scubapro wing. DSS is out of business but Highseas Millwork picked up the design and sells the same 55 pound wing with some improvements and cosmetic changes.
The Scubapro cam pack has holes to accommodate bands but they follow an older recreational standard in terms of hole spacing. Consequently, an issue is that the standard tech hole spacing is 11" and the Scubapro spacing is (IIRC) shorter, but the DSS/Highseas Millwork wing has lots of grommets and a pair of them will probably work.
However, in the long term if you are pursuing technical diving, you are way better off with a standard kydex or aluminum technical diving plate as they will be wider and offer a bit more stability with doubles than the Scubapro cam pack and a plate and harness won't cost much more in relation to the cost of the wing.
If all you want is to be able to carry doubles in recreational settings, you might want to consider the Scubapro "Litehawk" - it uses a very comfortable and slightly wider cam pack with a 56 pound wing that is doubles capable. And the price is very affordable by BC standards and won't cost you more than a technical diving wing by itself.
