Haha, yes, you are right!
One thought, perhaps was my feel that it drives more sluggish because it could be that the ATBs not only do what they are supposed to do, namely prevent the spring from winding up, but that they also somewhat impede the actual spring function and the spring is somewhat dampened in its up and down movement so that the spring no longer responds as finely. It's just a thought and other members know more about these causal relationships.
I agree Heinz. That was the main point I made regarding the coil sprung 5 link rear, be it factory or SSL. Axle location (particularly needed under hard acceleration) is separated from the suspension medium.
In the OP's case I would still be influenced by the videos @mph posted though. Given enough power available and used, the unrestrained axle wind up could potentially cause damage and won't stop leaf spring action being compromised. Given this ATB's may be the lesser of two evils and hence why factory fitted.
