| As a few others have said, don't bother with SCR if your goal is CCR. They are two different branches, not stages on the same route. As a homebuilder I also wouldn't recommend CC'ing a semiclosed unit without a good bit of rebreather experience. If your diving is <40m then I'd stick with OC. An Orribleanus is just overkill for that kind of diving. If you are planning more >40m diving then definitely go full CCR, I wouldn't even waste my time doing OC trimix any more.
