I used to use it a couple of years back.  I chose to drop them because of some
side-effects I saw in games, dealing with tactical issues.  They may do find on
test sets, but in longer games, they seemed to produce an occasional error or
two too many.

You should always test for yourself however, as every program is different and
will respond differently to the same ideas.
