Good choice! Times are pretty reasonable. Id be a bit careful of
setting to 250 all the way through though, IMHO better to drop
back to say 242 or 240 at first crack; this will give a bigger gap
between FC and SC. For example, for harder beans Ill leave it set
at 250 to FC, then around 240 for three minutes or so just to
a few snaps of SC.
Youll need to experiment to get best results -- keep records!
