Yes, seen and used that technique. Works a bit better by having an extended loop to get the peg/stick deeper, and the strength really only comes once the repacked snow around and above it freezes hard. To be honest, I probably could have done a much better job of pitching the tent - or at least adjusting it afterwards. I really should have gone out and cut down some long branches and re-peg out the tipi, or pegged it out initially using deadmen but with the pole deliberately shortened, and tightened up after the re-freezing, but seeing as I was well sheltered from any wind by the surrounding trees and still had plently of space inside the 8-man tipi as it was, didn't really see the need or energy expenditure justification for it (ie I was too lazy..)! Will do a better job next time......
