I'm looking for a folder that will pack easily into an airline-legal case with as little disassembly as possible, and fit under my desk at work if needed. I guess that means 16" is the way to go. And I'm broke as hell so I'd like to stay under $500. I'm 5'11", 220, and I'd like to be able to support the weight of small backpack for traveling -- on a rack, or on my back if I end up having to carry something else with the rack unexpectedly. Which would be best for me? Seems like the DT Mini and the Curve D3 are the only options but are there others?
