Mark Smith was famous among crews for having the same downhaul line on his Nacra 6.0 for years. In the bar, we called it "the Saw." Had a life of its own. He tried to put it onto his first Nacra 20 - I bought him a new line. He complained because the new line was so limp and he could "see it stretch." I'd bet Amsteel would feel the same as the Saw only slipperier! Bad combo...
