I agree that it's hard to find a cfi familiar with your EAB and your avionics. I advocate a two-pronged approach. First, sit in your plane on the ground, with aux power, playing with the avionics, for many hours. Not minutes. It can be helpful to have a knowledgeable person (need not be a cfi) help out, pose scenarios, etc. Once you are comfortable with the button pushing, call up the AI and HSI displays. That should look familiar to most cfii's. Explain the basics of the panel to the cfi, and go fly. Not perfect, but the last place you want to try to learn the button pushing is in the air.
Bill, as a previous poster said, insurance companies are in business to make money, and they do that by controlling risk. Yes, letting someone else fly in cruise is low risk. But not zero (speculation is that years ago a Vans demonstrater was lost in flight after the 'passenger' pulled hard and exceeded the wing's limits). Furthermore, would an insurance company 'count' that type of experience, with no landings? I sort of doubt it. OTOH, if, say, you choose to fly phase one uninsured, then apply for insurance, you will most likely not be required to get any dual. But even if you are, at that point, it can be legally done in your airplane so it's not relevant to this discussion. But what is relevant is that getting pre-first flight training for an EAB, in a legal and financially safe (no question about insurance) way, remains a rather expensive proposition.
