Interesting. I believe that this is the HF part that JJ is talking about.

Question: is a solid rubber tire, versus pneumatic, an issue for a tail dolly? I had put a solid rubber wheel on mine years ago due to a flat tire and caught all sorts of grief from nay-sayers. Something about vibration from uneven ground being transmitted into the boom with ill effect.

Thanks.
