I may have an answer to the question about whether #Jaspers or #Innox #keyboard #racks are better.

I had been working on the basis of Jaspers for heavy keyboards because the secondary clamps seem to offer better protection against rotation instability, but for lighter keyboards it don't matter too much...

The hand-turned knobs on the Innox clamps are as tight as I can get them without using a wrench instead. (Which would risk the threads.) But.
