| If it helps, what I've just done to cater for the diving that my club does whilst at the same time trying for as uniform a configuration as possible, to help in preparation for Fundies, is to have twin 12s and have a single 15L with the single tank version of my twin wing with its own set of regs.
That way I simply change the backplate over depending on whether I'm doing a wreck dive or a reef. It also helps as the club tend to do a wreck in the 25-35m range in the morning and a drift in the afternoon and mid-week, so it also means I have enough gas for the whole day.
Not the cheapest option at the start, but I think that over the long term it will save money on fills and help me to get used to diving the same system.
