Hey all, I have been out for awhile, so first post in several months.

I recommend 1 inch tubular nylon for emergency rappelling, if it becomes necessary. It will work for rope and a Swiss seat. You do also need a carabiner. You will need to put extra wraps in the biner just to get enough friction(I recommend 4)and you will still descend rapidly. However, it takes up much less room and weighs much less than regular rope. Yes, I have used it quite a few times myself. We used it for descending from trees on parachute jumps that went wrong. It will not survive many times being used this way,the friction tend to melt it. If you have the choice, replace it after one use. It is still probably too cumbersome for EDC to the office, but it is safer than 550 cord.

But yes, if I had the choice of burning or rappelling with 550, I will rappel.
