Before OPC/LPCs, I always spend a little time going through the notes/books/FRC drills. Might be superstitious, but it's worked so far (apart from the one time I was dropped into a no-notice Bo105 session with my previous employer. Sorry, Mike - I wasn't in the least bit ready for that one
)
...and having just read AnFI's contribution before posting, I have to say that in my current job I'd rather have a single-engine failure in my twin when working below 100' on the powerlines than 2 of my predecessors had in their mighty 206. Purely personal preference, obvs.
