I use my stand for both and have found they put the same amount of force. Spreader bar hammocks attach to the stand at a single point same as a camping hammock. It all depends on the angle of the dangle on both hammocks.
On TrailH4x's 2x4 stand he cut notches in his. You can make the same portable stand with out the notches. Its all about what you want in the project you build.
