The old school OME products are notoriously limited in their abilities, made for the OZ outback.
Bilstein has probably the best range of rear coils for multi-use applications. There is a 1" and 1.5" both using the OEM spring rates.
The whole idea of compensating for weight via springs is only really suited to dedicated overland rigs.
What shocks are you using anyway? The vehicle should never feel bouncy.
Bilstein 1" rear spring with Eibach rear shocks would offer great road manners with decent offroad abilities though the Eibach rear shock is not something I would take on the Black Bear Pass (poor travel) or something I would push here in the desert (because I will blow it

Been there, done it with Icon 2.0). But in Georgia, it would probably be prefect. The Eibach is better than Bilstein 5100 because it is a little comfier over small imperfections due to a strategically placed bleed hole or something like that. I have a pair as spares.
Back to basics, the ideal setup is soft springs with powerful, adjustable shocks but the cost of that kind of shock is 8-10X the cost of the Eibachs.
