Maybe ours is just the oddball, but then I have NEVER flown anything with a IAS or FLC mode that really worked that well. (Never flew an autothrottle aircraft)
Possibly I do not remember my times on the XLS well enough, I changed fleet to the Falcon in 2007... I definitely remember that we would hardly use FLCH for descent, but rather during climb, maybe not always. When you only have to climb a few thousand feet it will be VS anyway and not CLB/FLCH to avoid large rates of climb and upsetting other crews.
