Thanks guys. Think I'm about right on with my settings on my 798. Still like the blue screen the best, though I keep trying others. Everything else seems pretty much right on. I also rarely ever show/use DI, but was intentionally playing with it this past weekend again going over known stuff and it just wasn't showing much of anything - somewhat disappointed, but oh well. SI sharpness on my unit seems to be about finding that magic ratio/combination of boat speed, scroll speed and side imaging width, and less about the other settings. Some of my pics looks pretty good, and some not so Love it though, and I'll keep fiddling with specifics...
