Steve,
You responded to one of my first posts about a Techo-Block job I was working on. I remember discussing the rocking of blocks (and coping) due to the 'poor quality' of some of the block. On that job I ended up using some cement triangles as shims where the coping moved too much. Worked great.
You may want to look at this http://www.pavetech.com/newtools/ezshim.shtm if you are still having trouble with rocking blocks.
Take care,
John
