The 7/64" Amsteel seems to be really popular. If you're looking for a turnkey solution that's similar, consider Tethrd's "Mini VersaStraps". Like Amsteel, they are incredibly light, they are made of woven (not stitched) Ultra High Molecular Weight Polyethylene (UHMWPE) fibers, (aka Dyneema), and you don't have to go to the trouble to make locked brummels along the length. They're tree-bark grey, and they have a loop of shock cord on one end so you can wrap & secure the excess strap length around your stick and not have it flapping in the wind.
