I saw a post on a recent thread mentioning ditching panniers for some method of using water proof stuff sacks. I've been contemplating just that for weight savings, multi-purpose gear cost savings, plus a number of notions about carrying gear, water proofing, compartments, etc. This was initially inspired by the design of the Xtracycle Freeloaders and my own experiences with gear as an UL backpacker using a simple, single compartment, frame-less backpack.
I imagine this has been discussed but I couldn't pull up a similar topic with the basic search. Feel free to point one out. In the meant time, I'm curious what strategies are in line with my thoughts where a sling like the Freeloader, or a non-waterproof pannier like Military surplus canvas bags, are used in conjunction with something like DrySacks. I'd also want to hear the arguments against such an approach. I've been most interested in making my own (not the Drysack), and I'm working on the sewing project with grandma. So, the systems of construction and attachment are important while I creep through the project's planning stages
