my 2 cents worth ...

If you have alternate boyancy (i.e. a dry suit) you usually don't need a 
dual BC as if the BC fails you can get some degree of boyancy from the 
drysuit (within the limits of neck seals etc).

If you use a wetsuit then you need redundancy for your BC. If it fails and 
your are 15-20kg negative on the bottom it is a tough swim up. 

By the way, I have a Dive Rite with superwings - I like it, I understand its 
limitations regarding the shock cord, its effects on maximum boyancy and how 
to control it - and I defiantly elect to use it. I do not yield to stroke 
tauntings by hard line isolationist Hogarthian me-too GI3 lookalikes. 
(Theres an invitation to get flamed if ever I saw one !)
