You're right
Sometimes additional examples turns on more light bulbs

Yeah, but your wheelbarrow example sucked...
Nay a big solution for controlling flex on jeeps is the anti-rock bar..
Another awesome solution is the sway lock and is air actuated.
Welcome to Off Road Only!
It is a dual rate system... This means you can choose between a stiff and a soft swaybar ("Ant-Rock").
These guys are in MN. For the 80 and the front parallel 4 link I want to do I am thinking of getting some components of the system and fabbing the rest of the parts that need to be custom to fit.

They have an actuator which couples the inner and outer sway bar together on one side.
On the other side I want to be able to disconnect the inner bar from the arm with a second actuator. This will allow for Firm, soft and disconnected from the comfort of my seat.
Check out this online physics game. You can actually create little rigs that illustrate what is being discussed here. It's obviously rudimentary, but it can help you understand some of the concepts being discussed here if you are having a hard time visualizing it.

Oh man... I could play this game for hours...
well, the more Ebag333 posts pictures the more convinced I am that we're on the wrong track. The arm is only a place holder, it maintains the axle's distance from the frame, that's it (well also locks it in for caster). The truck rests on the axle via the springs and flipping the arms doesn't alter that.
The ease of movement is determined by the direction of the force that's being applied to the tire and the course that the tire moves in response to that force. In his diagrams with the three arms there is no difference in the course that the axle takes. So any given force will result in identical results in all three cases.
Now if Ebag333 can draw another set of diagrams but this time lower the rear mount. You will see three distinct different courses that the axle will take and the one with the least amount of forward movement will be the most responsive one to forces being applied from that direction.
But all that isn't really the question at hand. It's whether or not if it flexes better which is to say that there is less binding in the bushings with an arm flip.
carry on

more flex is almost always better --the tire that unfortunatly falls in the hole in Nays example of the overly flexable jeep will be the same tire that stays on the rock and offers needed traction when a stiff 80 series lifts a tire.
flipping a rigid 80 series radius arm is such a waste of time. if one is to spend all the fab time to flip the arms they could almost as easily make a 3 link or make a jeep-like radius arm set up (which has a joint the the "y")
note that my 80 has radius arms in the rear that flex like mad.
THE OE 80 SERIES RADIUS ARMS SUCK ON THE ROCKS compared to almost every other solid axled rig out there. the 80's only saving grace is its lockers and wonderfull rear 5 link.
The easiest way to make the front end flex like mad is to make a better radius arm. you need a joint at the "y". do this and she will flex.

Dusty, your 80 has some serious articulation. Did you do a "Y" setup in the front? It looks like it is just a single control arm with one link on the axle end.

Don't forget to polish your snorkel
front is a 3 link.
rear is a radius arm with a joint at the "y"
pics of rear are in my build up
anybody with 3-link/80 axle have problems i have thought alot about this and have wheeled with and seen dusty's flex like mad with his one tons....i have gone back and forth on which route to go, slee arms or 3 link i run 37" mtr's .anyone out have a report on long term use with 3-link/stock axle set-up, anybody have real life experience?
Hey, this is a family friendly site.
That's right, it is... Now get your mind out of the gutter!
Besides my snorkel has a textured finish........................

He's just jealous he dosn't have a snorkel, that's all.

speechless, can't even find an appropriate smiley face to handle that one
F***ing sensors at work won't let me play
That is probably a good thing. I have spent way to many hours playing that game during ethics lecture.
Dusty,
That makes sense now. I couldn't see that you had the 3rd link on top of the diff. Nice build thread, I had to force myself to stop reading it. D-60's seem to be the ticket but man that looks $$$$.
I don't see your point on the "y" link, your shock are just longer witch let the axle drop out, I would call that a bad idea with no control over your axle and loss of stability. Some times it's not all about flex.
