A few years back I was scheduled to do a charter for a couple of folks in a 44 Raven. One of them was physically large and simply could not fit in the rear seat (where I would have preferred him). The other passenger was normally proportioned. So, into the front it was with the big guy. My checks meant we were within overall weight limits and CofG with about half fuel, which was more than enough for the relatively short hop we were doing.
As I pulled pitch I was really surprised at how much the aircraft pitched nose down, and how much aft cyclic was required to maintain a hover. The flight was uneventful, but the foward moment on the CofG was major.
