Just getting into Canyoning as a great hot weather option during rock climbing "off season" Loved the few wet canyons we got to try around Ouray area this summer. I've got over 30 years as a rock climber and consider myself well versed on that side of things but have a few questions, mainly with differences in SRT vs the more common DRT seen in Rock Climbing. Looking at gear (I have much of it that crosses over) I see a lot of rope quiver recommendations with 2x 120'. Curious as to why that's preferred vs a single, longer rope (70/80m?) Most SRT rigs seem to be some variation of the Reepschnur setup. What advantage is there to 2x 120' vs a single 240'? I've read through at least 2 technical books and dont recall an explanation for this. Does it have something to do with avoiding having to pull a lot of rope through an anchor?
