2 GriGris to toprope with less rope drag

Sometimes the anchor is placed so it is almost impossible to come down from the anchor without creating a massive rope drag and wear of the rope. If you want to toprope such a route, one possible solution is to pull down an extra full rope length to the ground and "tie in with a Grigri", including a safety knot below. Then you can climb and your partner pulls in and belay like normal. Once at the top, you just take out the safety knot and rappel down with your GriGri. It should be mentioned that the suggested method should only be tried on routes where you do not take multiple falls. All falls, will wear the rope so you should absolutely not fall several times on the same spot.

Before you start doing this advanced technology make sure you put safety knots on both ends of the rope. Remember that you need as much rope below the climber's Grigri as the route is long.
