I know Fin had some sort of crazy plastic 2" plastic buckle on his BMB but there is only on Fin around here. I aslo tend to think that If the DC got bigger then is isn't a weight savings over a nano biner.
Or, if K.I.S.S. is your bag, small SS "S" hooks would accomplish the same thing, and weigh next to nothing.
Remember, though, that once you really crank down on a tarp ridgeline, getting it loose again can be challenging. For this reason, you should consider a nice, smooth toggle on one end, so you can just "pull the pin."
