the comments on frogland are slim on rack suggestions, i'm curious if any of you have recommendations for what I need doubles of, what merely singles, i'm assuming no triples? also, there is minimal discussion of linking pitches with a 60, with references to simul-climbing. bringing my wife up= must avoid all simul-climbing. but I could bring a 70 (or an 80) if it saves a pitch. my lightest rope is a 60 tho so if the longer rope confers no significant advantage, why deal with it? thanks.
