I don’t care about brands much and look more at $$, and the grams per meter who cares either, a difference of 5 g/m makes 300g diff on a 60m rope which weighs 4kg anyway. Stiff-handling, heavier, dry-treated ropes (like Edelrid Dry), last longest, if that’s yer criterion.
By the way I don’t know how Bluewater get away with charging the high prices in Aust, in the US BW is the cheapest rope you can buy. I suppose it’s like European cars, put a big price on it and people think they are getting something better…..
