the prussik is pretty fuckin safe in my book. if you're really worried, use another prussik and attach it to your harness.

quit worrying about everything being redundant.

Prussiks can, and DO, slide. Particularly when shock loaded.
Damn right they do. I found that one out the hard way. When I was a little kid I was prussiking up a 10.5 mm rope in a tree. Half way up I grabbed on a branch and slipped. I fell at most 4" on the prussik yet it slipped all the way down to my second prussik. Had I not had a second one I would had taken a ride all the way to the ground. Had I not had a second one at all like the OP, I would have hit the ground. Oh, and even with only about 2.5 feet of slippage enough heat built up to melt through 30% of the top prussik cord.

OP: If your going to use prussiks to ascend a fixed line you must tie them in a configuration so you are supported by both of them. There is an extremely good illustration on how to do this in the book Climbing Self-Rescue: Improvising Solutions for Serious Situations. I highly recommend you read it.

You can read it here:

http://books.google.com/...ge&q&f=false

Look on page 110 of the book. It shows you how to ascend using prussiks safely.
