The Sterling Marathon series are great ropes. My first was the Marathon Ultra 10.8, i think, and was a real workhorse. It held a lot of falls and took a lot of drag. I eventually cut about 15 feet off each end and continued using it. Now I use it for hanging TRs. I just got the Marathon sport in green this fall and enjoyed using it just as much. For my money I'll take a big rope that is gonna hold up, how many of us really need a sub 10mm rope?
