Tom, this is what I am saying. If people do a little home work they can find a system that is simpler, more efficient, lighter, and more suited to their individual needs. Im offering a little info to help folks uncomplicate their rigs.
The 2:1 I mentioned is a system that you can use fine on your own but, if needed, it allows people on the ground to assist you. I'll post a picture when I get back. It's really simple.
I always carry tiblocks, an eye to eye cord, 2 micro pulleys, and some 60cm slings. Sometimes a gri gri.
I use a light version of this for the effective 2:1. For ground aid, all you have to do is advance the ascender and the folks on the ground pull the rope to lift you. Repeat.
