Hi
Have you checked if there is a noticeable difference between FAC computed green dot, F,S and VLS and FMGC computed ones? If this difference is similar from flight to flight in the same airplane and in the same sense (FMGC speeds 5 to 10 kt faster than PFD speedstand you notice less speed stability and more difficult flares) then that airplane can have a problem with teh probes or the computers.
If this is the case, fly at the FMGC speeds and change VAPP accordingly so you can benefit from GS mini.

I wish my airline was like yours. I have met quite a few former sabena captains and they all love hand flying and I think they are probably the best captains I have flown with in all aspects.
cheers
