I would mention that while holding the inside straight in
FPDW is the correct play, it is a relatively marginal play,
and people who choose to not hold it are probably only giving
up about 1/10 of a percent EV in the long run. Now that is
not a significant amount but for the discerning player
probably not insignificant.
To me, for a while I perceived the correct hold as an
annoyance, something that slowed down the rhythm of my play.
So I played for some time without holding it. Other factors
that might offset the 1/10 of a percent sacrifice (besides
speed and rhythm of play) include the possibility of a typo
when you go to hold your cards (finger slips, etc.). If you
have no hold, you will have no typo. On the other hand, you
might miss an outside S4 (9,10,J,Q e.g.) if you look at it
too quickly and throw it all out by mistake.
In the end, I decided to go back to the EV-correct hold
because my feeling was that in my case the offsetting factors
did not overcome the theoretical 1/10 of a percent difference
in EV.
