Another shock question...i know i know...

72 Duster, steel headed 440, PST 1.03 bars, QA1 uppers, lowers and strut rods, Hellwig sway bar, B Body SS springs and mini tubbed.

I currently have RCD Bilsteins front and rear, but they seem pretty stiff. Even when I sit on the front of the car, it barely moves. Car sits pretty low, so I don't want to get softer bars if I can avoid it. I'm not sure if it's shocks or the t bars, but I'd like to soften it up a little. Over good roads, it rides amazing, but the potholes riddles ones will rattle my fillings out. Would QA1 or Fox or something adjustable be the way to go? The rear doesn't seem to be too stiff, just the front.
