Dead wood and some building clearence on this oak included the removal of a 12 - 14 inch horizontal lead over the chimney and deck. Lots of cutting smaller sensible pieces all double roped and tag lined away from structure. You can see all of the saw dust on the roof.
Correct me if im wrong but didnt treestuff have a hand in the design of the edelrid talons? Spikes should only ever be so comfortable so you hurry up and get out of them and only so light that by the time you start feeling their weight you have a big saw hanging on your saddle and its all down...
