No reason other than novelty. I haven't made a no FF or non-IFR trip in
a long time.

Next time, I will use FF if for no other reason than just out of
courtesy to other pilots. "VFR I'm talking to" is a lot better than
"unknown VFR".

Another reason would be to get continuous altimeter updates...
especially important on long x-countries where you may be a hundred or
two feet off after a few hours.
