Who is running superior super flex arms?

Who is running superior super flex arms? Whats the best set up to make these arms flex? e.g front and rear spring rates ect.
If you have any good pics showing the front end flexing post them up.

In R&D we found that if you were to go a bit heavier on the rear coils this makes the front end work a lot better as far as flex, it also stops a lot of body roll.
My red GQ is over 3t with 270lbs front coils EFS and 280 lbs rear coils EFS, this worked pretty good but slow it was a bit bouncy in the rear, and high speed the ass end was a bit prone to bounce on the rebound after going over a jump ,the front with super flex arms was good. high speed driving was okay.
We changed the rear coils to 340lbs dobinson coils and massive difference in handling both high speed as well as slow speed.
No less flex in the front or rear ,if anything the front flexed more due to the rear being a bit firmer and forcing the front to flex.
I run no sway bars front or rear , tough dog front 4" 80# cruiser with towers lifted 2 inchs, rear is 18" FOA remote resovoir with long arms and standard top mounted arms, hydraulic bumpstops.
This setup easily can be driven in rockcrawling or high speed events with no changes to anything.

Mine currently flex a little better than the stock arms and I have heaps of body roll so I need stiffer rear springs to reduce the body roll and make the arms flex more.
What rate works for different rigs is the ? SWB, Wagon and utes!
