For common black poly airline at 5/8" ID (sold as 1/2") plan on one half pound of weight per foot of length. One hundred feet of weighted 5/8" ID airline weighs 50 lbs. Weighted airline is very nice if it fits into ones budget. No kinks, no sharp edges, no snagging, quick installation, and easy installation. Hook it up and go.
