Agreed, it's more complicated, but at first I had thought that working smarter would have meant not working harder. And (what I had thought) the brilliance of inverting the Grigri meant I wouldn't have to mind any prussiks, or reset anything after each stroke (both physical and cerebral). In fact, all I have to do is pull, reach down the line, repeat - the Grigri locks automatically and does all the reseting for me.

Or, when I get tired of pulling, I could even take my second ascender, invert it and attach it to the haul line at the end of the z-pulley, tether it to my harness, and begin doing squats until the pig arrives at the station.

OR... maybe I should just shut the heck up and try a bunch of these while I'm out there. I suppose it all comes down to the fact that I really don't know how much weight it takes to make space hauling uncomfortable (correction, more uncomfortable) to the point where you want to try a more complicated system.

Oh, and thx for the suggestion about tethering the first inverted ascender to the anchor. I did, actually, lose it the first time while practicing....
