[KOML] What Color Negative Film Do You Use?

["James Upton" <jupton@zdial.com>]

    After shooting 3 or 4 test rolls of outdated B & W
film and finding that my recently acquired RO200 was
mechanically and optically OK, I thought it time to try
it out with color film.  To this point in time, I have
been using Kodak PRN-100 and VPS160 in 4" x 5" format.
Although both are still available from B & H and other
sources, they have been discontinued, replaced with
Portra 160VC and 160NC.  I chose the VC (vivid color?)
to start with.  I have the finished prints and
everything looks fine, however, the custom
photofinisher tells me that Fuji NPS160(D) is a better
color negative film.  He also told me Kodak had
withdrawn the Portra films for a while because of
(problems).  BTY, one problem he described is a very
light streaking although it doesn't affect print
quality.
    Well, I've been a Kodak user since the beginning of
time, and opted to try a couple more rolls.  This time
using 160NC (normal color?).
    One final note;  Cost of developing plus 10  4" x
5" prints was $8.15 plus a cut for the Pennsylvania tax
system.  Price of the film was $3.95.
    Any comments will be appreciated.
