When you had the D200 converted David removed the LPF and fitted the IR filter effectively blocking UV and visible light. The anti-aliasing 'filter' went because it's a component of the LPF. in fact as I understand it, it's simply a micro ripple effect on the surface of the LPF which creates sufficient blur to stop any moire effect in images.
Removing the LPF should have resulted in a sharper image but as you say IR images do tend to be slightly soft so perhaps I was being silly (again)!
Not really...it's a complicated picture, because one doesnt really know what the AAF would have contributed in the IR spectrum.
