I'm thinking we're saying basically the same thing...no?

The number of links is not going to be what affects ride quality, which is a completely different factor than flex. If you want stock ride quality without sacrificing handling, I'll say again to get the FOR kit, because that is exactly what you get.
After I put the Gen II kit on last year and the new 37's we went to Moab and

The issue is that the 80 rear suspension is pretty unhinged - it's where all the motion wants to occur onroad, which is why most 80 series kits have overbuilt rear suspensions that ride like crap unless you add a ton of weight.
This flexy rear is very much controlled by the front - I'm not saying that you can't unhinge the front and find a way to keep it all stable and I haven't tried it myself, but we all know that a lot of engineering has gone into trying to control the much lighter quad coil Jeeps at less than 6" of lift so assuming that adding a ton of sprung weight and having it all unhinged on a tall lift is to me a very big assumption that has absolutely nothing to do with ride quality.
I'm not saying any of this to be negative, but rather to spark some thinking about how to solve for both issues. You might talk to Dusty - he has 3 linked and raves about the offroad improvements but noted the deterioration of road performance.
The net observation from my web wheeling point of view is that the issue is not the 3-link. It's the 3-link paired up with the stock 4-link rear and how they want to work together. You change the one and it is pure assumption that it will be enough to leave the other alone.
