The sticky ropes have never failed to get me home. The stop n go plugs don't work so well in steel belted radials. Picked up a drywall screw in a rear Tourance, and plugged it quickly with my brand new stop n go. 50 miles down the road the tire went flat again, the soft rubber plug chewed in two by the steel wires. Re-plugged, and that one lasted 49 miles. Finally tried the sticky rope, and it was still holding fine 1,800 miles later when the tire was replaced.
