Ah, I get the idea. Have a feeling that the Durst Nega 138 is pretty 
good at clamping the neg carriers fairly tightly so I may not have 
the option of a "kissing" rather than clamping contact. Am hoping 
that the design of the neg. holder is such that the neg is just held 
in the glass rather than clamped. Haven't tried this out yet.  Guess 
it'll have to wait until I return from a trip after the weekend.

The top glass will be fine as it is anti-Newton ie slightly frosted. 
The bottom glass has the potential for rings but will keep my fingers 
crossed and try not to raise too much dust ;-)
