Van den Huls are high compliance. At new, they can be VERY tricky with tracking until the suspension breaks in a bit. Then they’re nice carts. I just had to stick with it and not give up. Used them with both low (VPI) and medium-high mass (FR64fx) arms - honestly didn’t notice much difference based on mass.
Most MI (like Grado and SoundSmith) and MM carts tend to be high compliance, because these designs do not feature the stiff suspension string and stout damper typical of most MC designs (they can also be more fragile due to this). Van den Hul is the exception, making MC’s with relatively high compliance.
