Having flown with airlines, I am just about to retire in a few weeks.
Throughout my aviation career, I am often around small private airfields.
Even own a Piper L-21C (a former military Super Cub).
And of course have acquaintances who own/fly light twins.

If flying a twin with powerful engines and good single engine performance, fine.
But beware of low-powered twins, and heavy payloads.
Besides all that, try to maintain adequate engine-out proficiency as pilot.

I have a preference for my little tail dragger. I can land it about anywhere.
Twins have double the engine failure rates than single engines.
Statistics - If engines fail every 4,000 hrs, twins will average one each 2,000 hrs.
I agree to the mention of system redundancy, i.e. generators, vacuum pumps.
De-icing, dont believe in it too much... and call it anti-icing.
If you enter icing conditions, your best procedure might be a 180º turn.
For me, lightplanes, single or twins remain restricted to VMC and blue skies.

I have a friend who owns an old PA23 Apache - 2 x 160 hp...
Last year, one engine failed, he had to land it on a road in the country.
Had 4 adults on board, could not keep it flying to the nearest field.

Have fun guys, if you can afford the extra gasoline. And fly safe.
