I hear you. I'm quite interested in utilizing CM's alternative head options because of the obvious possibilities, but there are so many variables, it may take some time to sort them out.
As far as first impressions with CM's AMH, the immediate difference from RMH was the unique sensation of ALWAYS having my eyes (i.e., the cockpit camera view) pointing in the direction I SHOULD be going (i.e., the racing line). For instance, I might be starting down Hangar Straight, but if I'm off the racing line, my eyes are fixed those few degrees over to the side, urging me ever so slightly to the left, even if a fellow competitor is flanking that area. In some cases, AMH made it quite a bit easier to save a massive slide: as the saying goes, always keep looking where you want to go, not where you're headed. Conversely, the use of CM's AHM definitely seems to cast a very bright light on untidy, amateurish driving (e.g., having too much steering input from the driver for the curve or chicane. From that point of view, AMH is a fascinating Track Day instructional tool (at least with its default settings). I'll have to fling the 718 RS 60 around the 'Ring for a spate of laps to determine if it's "best-practice" for us single-monitor, non-VR/Track-IR drivers.
