Since top roping done right allows the person climbing to fall without creating a lot of force, I should be able to use a static line for greater abrasion and degradation at the bend resistance. Any opinions/experience with that?
Also, knots in your glacier rope, between people, in order to help slow or stop by catching the lip of the crevasse:
1) does it work
2) if yes to one, what knot is recommended
3) how does one get the knot out, under load, in order to ascend said rope? or does one have to be hauled out at that point?!
