Any reason that you aren't using the same rope as both tether and rappel line? I'm planning on using the rappel line for both and just connecting autoblock/atc for the way down. Thinking I can hold the prusik (the one I tether to bridge with) loose in left hand as a backup while using right hand on autoblock. This would eliminate needing to swap ropes and always have you connected and under load. Or been there done that and doesn't work?

I was planning on using different ropes because I didn’t think my distel would slide right and didn’t want to have to untie it. And because I just bought that setup, dang it!
