| I've been pondering this one too, my YBOD will be arriving "soon" and I'm basically stuck with doing the IART course due to Instructor/unit availability, this is fine but IART insist in dragging the training out to 3 courses. I really don't see the point in their "extended range" course, 60m with no He but it will be a prerequisite for their trimix course. I expect I'll put He in when I'm ready as already OC trained and just not push the depth until I feel comfortable.
