Staged multigas diving is not suited to recreational diving. Primarily, it is not necessary and offer very minimal benefit. Nitrox is well suited to rec. dives. Really guys, 2min O2 safety stops, recreational deep stops, recreational 40 ft. gas switches... How about a little realism. Why the complexity? For the sake of "show". Why not no-deco, recreational Trimix... hmmm, hypoxic safety stops or gas switch?
