Progressive 444’s on Amazon for $505

Does anyone have an opinion on the 444 vs the 430 series?

The 444s are their high end shock. From their website - The 444 Series Shocks feature a proprietary patented Frequency Sensing Technology (FST) that has the unique ability to dynamically adjust damping as you ride; what this means is whether you’re hitting the small or big bumps in the road, the shock distributes oil through ports accordingly to soak up the hit making for an ultimately comfortable ride. The 430s don't have the FST, but rather a deflective disk damping system.
