I`m not sure you are getting the message.
You are operating a multi,out of a strip that is shorter than the recommended,adding all the factors,or even not! I think you have a rather large bag of "presson-itis".
What may have happened if you had been able to unfeather,but not able to restart the engine- would you still have tried to make it home?
If the engine fails ( and it`s not a pilot digital induced fault)
then shut it down and leave it alone--- except if you are somewhere you really need it,ie mountainous and as a last resort--see reason above!-I hope you were not out to impress your t/p friend- who incidentally should have strongly suggested you go elsewhere as he should know better!
