Hey slaw,
Your question in regard to the bearing material is absolutely correct. Also, thanks for the info on the balsa/carbon fiber material. Seems like it would be a good choice for an equipment platform, but you never know... Hence, I'm going to take your advice & buy a small amount of it first, to give it a try. I'm also going to try the solid carbon fiber & probably the birch version. It's interesting on their site (dragonplate), they have thin carbon fiber backed with linen they claim is good for reducing vibration. Probably worth trying as well, just at the contact points.
