Hey Joel: I'm also one of those guys with a Huki OC-2 and special iakos, but you also have to understand I do most of my paddling in Indiana - not exactly a hot spot for big waves.
I have, however, raced my OC-2 on Lake Michigan with a friend as a K-2, doing quite well for our skill level. It's great to be able to just keep on paddling full-bore through very rough conditions (wind-driven waves combined with wakes from large boats on both sides and rebounding waves off sea walls). Not having the opportunity to train much in those conditions, racing an outrigger with kayak paddles gives me the stability I need to run my best. So - no "flying the ama" at the moment (hopefully I'll get on some bigger water before long to try my hand at it), but I did get a chance to play in some motorboat wakes. The OC-1 really picks up the wakes nicely and rides them with ease.
I adjust the ama to basically keep the hull level with me in it and to keep drag to a minimum.
My paddle didn't really seem to need much adjustment; I probably use a more vertical stoke in the outrigger than in the surf ski, but the Scorpius XS sits fairly low for an outrigger. My paddle is an Epic mid-wing 215 - 225, and I kept it at 215.
