Don't bother with worring about "future needs". Fact is reguardless of the BC you get, you are going to have to buy another one if your diving changes a lot. Even the much touted BP/wing is no exception. Going from singles to doubles you will need to change so much (wing, bands and other bits) and is such a pain in the rear the swap out that you will end up with multiple back plates and harnesses. Even going from cold local waters to warm tropical waters makes owning a different BC very desireable. The steel back plate and 50 lb wing perfect for cold water is heavy and bulky and with airlines the way they are today a lot of unwanted weight and volume. A light travel BC is really called for. Forget the one size fits all approch, it's not realistic. Sure you can press one BC into doing it all but it will not be anywhere near optimal. Find a BC that meets your current needs without breaking the bank for now and plan on buying another one or 2 as your diving needs change.
