The cam-cleat for the main sheet on my AI works just fine. But I didn't like having to reach up so high to pop it loose and then hold it up there while trimming the sail. So I mounted a run-of-the mill old fashioned cleat to the starboard gunwale just forward of the seat. I run the sheet from the forward harken block under the Ama crossbar. No tangles and I can trim the sheet with my hand resting comfortably on the gunwale. I recognize that I can't just pop it loose in a sudden gust, but it's not a big deal if you stay on top of things.
Subjective, of course, but I find it easier and more comfortable.
