Depending on the hammock you use, you should seriously consider a longer ridge line on a tarp, in particular with the HG 4 season Cuben tarp, It's not as wide as a Warbonnet Superfly, on those stormy windy nights you want your tarp down low, a longer tarp will cause some problems on those stormy nights with a blackbird hammock.
My personal opinion: I don't think the longer tarps for a Blackbird Hammock is a wise decision.
