When I worked with the Eversmart Pro I owned two glass beds and used the one with abraded anti-reflection coating for fluid mounting. The fluid basically fills in the scratches on both negatives/transparencies and on the scanner glass. I also owned a fluid mounting station with a glass bed, but did not use it very much since I found it very easy to just fluid mount on the regular glass.
The Eversmart literature that I have seen recommends fluid mounting only with magnification of 8X or more. I personally fluid mounted virtually every negative I scanned since I never saw a drawback in doing so, and in many cases the fluid mount was superior in terms of contrast, grain smoothing and/or eliminating the appearance of dust and debris.
For securing the negative to the glass I used 3-M blue line masking type, same type you can buy at Home Depot or Lowes.
With regard to the ppi limitation of the Eversmart Pro, it is 3275 ppi, and it is the only scanner I ever tested with a resolution target that actually exceeded the advertised resolution.
