When I got my Filco MJ2 TKL Ninja with Cherry blues, I replaced the keycaps with the classic beige with blue set from Originative. When typing, I noticed that I often had typos where the "g" key was hit when trying to strike the "t" key, so that "the" came our as "gthe". This occurred most often after first typing an "f", and so I thought it might have to do with the fact that the F and J keys in the replacement keycap set are scooped, because I did not encounter these errors with other keyboards, such as the IBM Model M, IBM SSK, or Leopold FC660M (with Cherry blues), none of which had scooped F and J keycaps.
To test this hypothesis, I switched the F and J keys on the Filco with the F and J keys on the Leopold (which have the dye sub PBT Cyrillic sets from Originative with underscored F and J keycaps rather than scooped keycaps). The result: no errors on the Leopold with the scooped F and J keycaps, but the same errors on the Filco with the non-scooped keycaps. The alignments and heights of the keys appear to be fine on both the Filco and the Leopold. Has anyone else noticed this problem?
I suppose that this issue merely reflects poor typing accuracy on my part with perhaps a higher sensitivity (or "better" NKRO) on the Filco than on the other boards that I use. In any case, for my own use, this puts another minus in the Filco TKL column and another plus in the Leopold FC660M column, further contributing to my current selection of the Leopold FC660M as my second-favorite keyboard (next to the IBM SSK).
