Funny this topic should come up. I was just having coffee the other day with the CP of a company here in New England that has two MU-2's (used to be more). They've been flying them a long time. He's got well over twenty thousand hours in the -2, and loves it. He did say that they use Howell. He didn't have a lot of respect for these so called "experts" that write articles to trash the airplane, that don't have any real experience with it.

So, look into Howell I'd say.
