i have been climbing on an icicle for years, you can get much closer to your anchor because your prussik doesnt dissapper round the tree! i have mine as short as poss so there is no ́sit back´. you will need to get the right diameter for your rope, i use 8mm prussic on 11mm rope, (use 9/10mm prussik with 13mm rope) and a small swingcheek pulley(fixed are ok, but theres not as much flex) this knot does get tight and needs loosening at least once per tree but you just open it up a bit like you do a prussik. heres a vid of how to tie it: [ame=http://www.youtube.com/watch?v=N5cr8I_tJTI&list=UUqawqLWn9o_UYvP2ovAKRLw&index=12&feature=plcp]The Icicle climbing knot - YouTube[/ame]
