I've completed the new bearings for my Lightbridge 16, and at present I'm pretty happy with them. I've increased the size of the altitude bearings, and pretty much halved the height and weight of the rocker box.
The altitude bearings are slightly offset, so that more weight is behind the axis when the tube is pointing towards the horizon. This means that with an Ethos eyepiece I don't need any weights on the bottom of the tube. My 1.25" plossl is just in balance, but my lighter plossls make the top of the tube bottom heavy...
I've put some photos and a description at http://www.batchelors.net/personal/telescope/16-inch-meade-lightbridge-telescope.html. The update with the new mount is at the bottom of the page.
Cheers, Peter
