My longest dive to date is 60 minutes under water and I don't in the foreseeable future expect to dive much longer than that. If I did want to do longer or deeper dives (with decent bottom time) I would have to log 100 dives and do technical diving or do CCR. CCR is expensive and I don't know what you would have to achieve before starting the course. Long decompression stops do not appeal to me either.
What would be so difficult or risky about switchable twin tank diving using either air or trimix from say 35m to 55m and nitrox for the shallower parts of the dive?
Not considering a large gain, just really a possibility of spending say 30 minutes at 40m then ending with shallower dive (upper parts of wreck or nearer shore) on nitrox.
