It's worth remembering that in order for an Instrument Rating to be used, you
need to meet recent experience requirements. It's not like riding a bicycle,
where once learned, it's automatic.

Unless you're going to file IFR and fly in the clouds, I strongly suggest you
invest in hood time so you can get out of trouble should you find yourself in
IFR conditions. I think, unless you are flying 150 hours a year or so, you'd
likely not be current.

Having said that, I can tell you that SEL flying, especially at night, under
IFR is a heck of a lot easier than VFR, regardless of condtions. I mean, think
of this, coming into your tower controlled home base, being cleared for an ILS
approach which probably means, unless it's a dreaded 'circle to land' a
straight in from 5 or 6 miles.
