on the amount of line... it depends how you rig it up... but the generic was is about 30'(10m) for the ridgeline, and about 5'-8'(1.5-2.5m) for each tie out... so you can do the math, or just save yourself the headache and buy the 180'(55m) spool and have enough for this set up and the next and some to hank up and throw in the pack...
