Not sure I understand you Robert....if the D200 hasn't got an antialiasing filter....how can it be perceived as stronger than ideal? I only have the IR converted D200, which as you know produces softer effects anyway. But that raises another interesting question ....what is removed when the IR fitted? When I converted the D70 I swopped over the LPF for the IR filter. I assume this model had antialiasing. So was that 'attached' to the bit of glass I removed? I can't say I noticed any 'above normal' sharpness in either IR cameras...so it may be only a minor improvement to sharpness unless you use a tripod and primes.

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.

Not sure I understand any of this ...the AAF is a micro-ripple effect on the surface of the LPF which greates blur, but would that not cause soft/unsharp images , KODAK omitted the AAF on the slrN claiming X-treme sharpness without it ?

The Micro ripple effect does cause soft(er) images, that's the point, but the coa**er grain (lower resolution) sensors are very prone to moir© which is very difficult to remove in post processing, so it's a trade off. Nikon have given users a choice with the D800E. It depends a lot on your subjects, Moir© would be a big issue for architectural photography for example. For portraits it may not be, but portraits tend to be softened anyway, so it's down to the users needs.

I dont think I have found any moire effects with my D800 or D600 and I tend to look for this especially in the fabrics of clothes in portraits.

For me the D600 (dust spots included, apparently they disappear after >4000 shots, only 1700 more to go.) is more useful on a daily basis. The D800 is great but it is bigger, heavier and its image size at 36MP is more than I need unless I want a grain free image blown up for the side of O2 Arena. Strangely I havent had too many of these requests. I really need to get out and find some banking customers!

Strangely I havent had too many of these requests. I really need to get out and find some banking customers! Whilst that is a very good reason for using the D600, it doesn't answer the question.... Are the smaller D800 pixels better than the D600 pixels? The 'grain free image blow up' you mention suggests that''s true and the conventional wisdom of best IQ = big pixels has changed? Using the 100% crop comparison method recently discussed... Does the D800 file look better at 100% in CS, than the D600 file? So many restless questions....clearly cake deficiency setting in.

Like for like at 200ISO I cant tell the difference unless I blow up on screen to 400% At 100% there is very little difference not that I have ever done an identical shot/lens comparison. I'll see if I can do that in the next few days if there are some good opportunities.
