It's like I said.. With a twisty I could do ~95% of what I do with the pedals. That last 5% is still a substantial difference... It's usually the difference between regular acm and the really precise "h4x" stuff, the exact shots from 600 out, and riding the edge of the envelope that fraction of a second smoother/longer. If I could control the head position with my own head, I'd probably cut down the misses on snapshots with the 152 by about 50%. That's really not insignificant IMO.
This is the same kind of thing as those tiny 100ths of a second per corner that add up to a second per lap in racing. It all adds up.. Discomfort with the way you sit, or if your screen is too bright, or if there's reflections from a light source around you, or noise nearby, or if your pedals or hats are slipping under your feet or hands, or if the controls' geometry or input scaling aren't optimal... It all easily adds up to the difference between the plane doing what you intend it to, and a train wreck.
