I noticed on the conecolor site that you have K3 profiles for the 2200.

Now it just so happens that for some years I've been printing in my trusty old 2100 using K3 CC inks that I initially bought for an R2400. I made profiles myself using my i1 Photo. I assume that your K3 profiles are made with the same CC K3 inks that I'm using, i.e. leaving out the LLK ink since it's only a 7 colour printer, and so I could use them if I so choose? (I'm asking because I thought that what I was doing was a little radical, but perhaps it was not so radical after all.)
Can I also ask a question about http://conecolor.com/icc/Printing%20With%20a%20Color%20Profile.pdf ? I realise that it's an old document, but I noticed that it recommends relative colorimetric intent on a Mac and perceptual on Windows. Any reason for this?
