I know Pros & Cons, but…
…when using it works pretty fine in case you are going for heavier carts than the TSD15 or other “Tondosen”.
here we see an Ortofon A90 mounted in a special & modern EMT headshell.
A Fidelity Research FR-7f cart with diamond connection also needs more weight. You can mount a different counter weight at the rear of the RMA 297 or you are using just this little device.

Very good idea, Pierre Clement tonearms have the same damping cylinder in wood , very useful for changing VTF on the fly…
