I did my initial multi in a C-310 and always enjoyed the security of having a decent second engine - and it paid off. During a later instructing flight with a student the same 310 developed an oil leak and we did a precautionary shutdown as the temps rose. Didn't even worry about bringing it in single engine because I knew that in a 310 you always had the option of going around.

But of course, then you get into the same problem a lot of guys have in initial type ratings in planes that can easily climb on one engine...they give go-around thrust/power and don't adequately control the yaw which can easily be just as or more dangerous than trying the landing.
