I also use the PMI verglass. Its very light and super slick. Its also dry treated and intended for alpine conditions. It is both twin and double rated. Some other company makes a 7.7 that weights the same amount per meter, I prefer the 8.1 for belaying and repelling. Cut it down to 50m and it weights 4.6 lbs... That's hard to beat, for the safety you get. If you pair it with a thin static rap cord you can do full length raps for little weight. jake
