"Can you quantity how much wallow? "
While I too would like to see an answer to this question I have to ask "Do you have a way of measuring wallow?" and "Under what load conditions?"
I fear that even if were measured most of us would have a hard time relating a number to our driving experience. Also, a high CG load like a slide-in camper or a load of firewood is going to cause a lot more issues than a low CG load like weight on a trailer ball or a load of gravel. I would think that if body roll is a non-issue for your load and the way you drive then the Sulastic springs won't hurt you too much. If you are getting noticeable roll now I think that it will definitely be increased with Sulastic springs.
Keep in mind that roll is caused by torque about the roll center of the vehicle. Roll center is pretty much the height where the leaf springs attach to the truck, generally near the bottom of the bed. The farther your load is above that point, the more roll that it is going to cause. I suspect that some of the issues with the old GM trucks with coil springs was that the panhard arm was attached to the frame lower than the leaf springs were and maybe had too soft of bushings on the panhard arm.
