Then I guess I lack the "skill to eliminate 'dust problems.'"

No Lab involved; I develop my own Ag-based films.  No scratch problems whatsoever.  SS 
tank?  Check.

Photoflo rinse?  Check.

Hang to dry in closed shower stall?  Check.

Distilled water rinse?  Uh oh.  Haven't tried that.  Since I have a roll of TMax in the tank, I'll 
give it a try.

Another problem I couldn't solve was film curl.  Created scanning problems in my Nikon 
4000 ED.  The C41 film I get from the local (pro) shop is dead flat.

I use PrintFile neg holders, and, indeed, they are polyethlene.  The manufacturer claims 
they are archival and better for not attracting dust.  What would you recommend as a 
alternative?

Might as well go digital?  Bite your tongue!  (As I fondle my M7.)

As for tonal scale, my feeling is that the printing workflow may have a greater impact on 
*my* images.  I use K7 piezo inks on (typically) HPR in an Epson 2400.  And since I don't 
do landscapes, perhaps I'm just not seeing the loss of tonal range.

(Also, I had originally mentioned the exposure latitude of XP2 which I find valuable in fast 
shooting situations and tricky lighting.)

Nonetheless, I do appreciate the comments/suggestions.  I realize there are some heavy 
hitters (ncluding djon43) here with vastly more experience than I have.
