• v5 Quite Difficult: Difficult rappels in moderate to strong water flow. Multi-stage rappels with hanging stations or redirects. Rope recovery difficult. Difficult and/or exposed climbs.
• v6 Very Difficult / Exposed: Very difficult rappels in very strong water flow with possible hydraulics or siphons at the bottom. Awkward rappels stations, difficult traverses, exposed and difficult climbs.
