The other thing you can do is borrow a -10 from a friend and have a qualified instructor fly with you. That's what I did, but it required jumping through some insurance hoops.If you don't have your own -10, you're limited to people with a -10 and a LODA for it. As far as I know, Mike Seager using the factory demonstrator (though I heard a rumor that they were cutting him off, but I don't know if that's true) and Alex DeDominicis in Texas are the only -10 LODA holders. Both are well reviewed.
