Golly.....I forgot possibly the most important comparison of all: The Pickup Test
My 950 was a beast to pickup....as in dead buffalo.
My F800 is quite easy to stand up....not that I actually ever fall down.
I said "Test" didn't I ?
Give that a try when you get your hands on each of these machines. Lay em over....then pick em up.
The difference was significant for me. But maybe I'm just a putz....I donno.
p.s. I'll happily receive either one as a free gift.
