Progressive suspension

Hello guys, I want and have to miss my SB other shock absorbers. The original dampers are simply too short (all nose length is something on) and too soft. Who already has experience with the dampers of Progressive Suspension? Are the 412s, or rather the 418s adjustable in the train stage? Or are the 440s the only true thing? I drive a lot with Sozia, and otherwise quite “dynamic” Need a good compromise between comfort and stability. Thanx Ronny
