I was thinking about getting a DMM Flight for sport climbing but I have 1 question to people that have one already. I would like to use my existing rope bag and not the tarp that comes with it. I have a Metolius vortex rope bag and I love it. I had a trap and drove me mad in comparison. Is there enough room in the DMM Flight to get a Rope Bag other than the DMM Tarp into the DMM Flight? Thanks.
