I don't think leaving your rope in the bag is the problem, I do that too. When I'm flaking my rope back into the bag I run it through my hands to help remove any twist.

One thing I'm not clear about is whether you're talking about the two legs of a DRT system twisting around each other above you (what I originally thought) or just the rope itself twisting, or both.

Ok, I just reread your original post. I'm mystified. You have to spin around to twist the two ropes across each other above you. Right? So either you are or your not. You can look up as you climb and check to see if you put twist in (two ropes twisting together) and correct by spinning around the opposite direction.
