Arguably the best specs for any half rope on the market, I have one teal and one burgundy New England Ropes Unity 8mm x 70m, 2XDry. http://www.neropes.com/product.aspx?mid=FC4DB29E596CB9D0D1DE3CDC00B982F1&lid=1&pid=59
Still tagged and in the bags, current retail price at Liberty Mountain right now is $234 each!
But I noted that one might be able to get these or similar products for around $350 for a pair, so I'm going with an asking price of $225. Don't make me keep them and have to perfect (along with partners) double rope technique.
