stock springs battle

Hi all and happy new year from Greece.
I would like to change the stock springs of an m38a1 with yj stock springs.
Because i'm going to make new hangers all around for yj springs, i want to get about 2'' of lift from the hangers.
What do you think is better for more flex,
to run on stock yj springs and get the lift from the hangers or get the lift from an aftermarket spring pack(old man emu).
You think that they would flex better than stock because m38a1 stock springs with rancho rs9000 for 2.5''lift flex preety good.
I can post some photos of the current set up

 

From what I understand, the yj springs, stock, will flex better than aftermarket springs. I also think the stock yj springs will give you about a 2" lift over stock.

 

Lots of good stuff on the ECJ5 tech pages...

Have you seen this article?

I've seen this article but it concerns a 4.5'' spring lift.
Would they flex better than those photos.

I recommend stock YJ springs OVER the axles. You gain both lift and flex. Couple this setup with some RS9000 adjustable shocks and you get the following:

Thanks for the input.
I think i'll choose stock yj and get the lift from the hangers, cheaper and same work.
