CORRECTAROONI!! And this is the way I'd go (i.e., parallel link pairs). When the link pair is parallel, it's equivalent to what's called a "4BAR" arrangement. I think Morrison sells them this way in a package which is somewhat cheaper (and, perhaps, a bit weaker???) than the 4link. I really can't say that the 4bar's are any wimpier than the 4link's. That's just what I've heard. You'd have to talk to Morrison. Anyway, it sounds like you're capable of fabbing your own, in which case you can make them as strong as you like.
Angle both link pairs up at an angle with a tangent equal to the CG height divided by the wheelbase and you'll have no squat or rise. Angle the right side an extra 5 degrees and the left 5 degrees less and you'll have pretty near equal rear tire loading on launch. Both setups will give you no binding during street driving.
